The impact of isomerism on electrochemical/electrochromic (EC) materials remains insufficiently explored. In this work, two electrochromic-supercapacitor (ECS) bifunctional materials pBQ based on pyrazine unit and pDQ based on pyridazine unit featuring diazine isomers are synthesized through direct (hetero)arylation polymerization. The impact of diazine isomeric units on backbone structure, EC properties, and supercapacitor performance of materials are investigated in detail. The pBQ base on pyrazine displays enhanced backbone planarity, higher color saturation of 51.82 in the neutral state and lower color chroma of 0.26 in the oxidized state, indicating reversible color-changing between a more vivid colored state and highly transparent state. Furthermore, the pBQ presents improved electrochemical and EC properties than those of pDQ, including more reversible electrochemical behavior, larger coloring efficiency (279.5 cm2 C-1), better cycle stability (retaining >90 % of initial performance after 1000 cycles), and higher area-specific capacitance of 2.61 mF cm-2. The prototype EC labels base on pBQ and pDQ are assembled, enabling updatable information capabilities and dynamic data management. This work introduces a novel approach to precisely enhance backbone planarity, facilitate color tunability, and develop electrochromic-supercapacitor bifunctional materials with highperformance.

Electrochromic materials and devices reversibly switched between the transparent state and the black state have great application prospects in fields such as smart windows, smart glasses, and smart car sunroof. In this work, a non-conjugated main chain polymer (P-YB) with triphenylamine derivative electrochromic unit and cinnamate photocross-linkable unit as functional side chains was fabricated by proper designing the molecular structure. The stable and insoluble crosslinked polymer film (F-YB) was further fabricated on indium tin oxide (ITO) glass via a photocrosslinking method initiated by UV light. Owing to the multi-step oxidized process of dimethylaniline modified triphenylamine electrochromic unit, F-YB exhibits no absorption in the neutral state and almost full oxidized absorption properties in the visible range, thus can change from highly transparent to a near black color with optical contrast of 40% and coloring time of 7.6 s and bleaching time of 4.0 s. Therefore, the electrochromic device based on the F-YB film was further assembled, which exhibits a reversible electrochromic phenomenon between transparent and near black states, and its near black-state transmittance is well-suited for practical dimming applications such as smart car sunroofs and smart glasses.

Viologen molecules have emerged as one of the most promising classes of electrochromic materials owing to their highly transparent bleached state and large optical contrast. However, the high redox potential and irreversible dimerization of viologen radical cations formed during the electrochemical reduction process limit their practical applications. Herein, a series of viologen derivatives were designed and synthesized by incorporating benzene-bridged units, substituted benzyl groups, and electron-withdrawing substituents. The synergistic interactions among these functional groups and structural moieties can effectively modulate the energy-level distribution and molecular spatial configuration of the viologen derivatives. It is intriguing that CNFBZPV bearing cyano and fluoro substituents exhibits a lower LUMO energy level (-3.32 eV) and more positive redox potentials (-0.75 V/-0.56 V), along with greater steric hindrance and a larger dihedral angle, which collectively contribute to favorable redox reaction kinetics. Moreover, an electrochromic device (ECD4) fabricated with CNFBZPV and ferrocene achieves a high optical contrast of 80% in both the visible and near-infrared regions, along with excellent coloration efficiency (233.99 cm2·C-1) and cycling stability, retaining 98% of its initial optical contrast after 3000 consecutive cycles. In addition, a colorless-to-black electrochromic device (ECD5) was assembled with two cathode coloring materials CNFBZPV and 1-butyl-1'-phenyl-[4,4'-bipyridine]-1,1'-diium bis(hexafluorophosphate) (HBV), and one anode coloring material TMTPA, which enables broad optical modulation within a low operating voltage (0.5 V∼-1.8 V), combining a highly transparent bleached state (nearly 100%) with a black state featuring low transmittance (less than 15% in the visible region and approximately 20% in the near-infrared region). On this basis, ECD6 with optimized thickness of the electrochromic layer and the encapsulation process exhibits excellent photothermal regulation capability as well as faster electrochromic switching speed (<5 s) and improved cycling stability, which can retain nearly 60% of its optical contrast after 3000 cycles, which demonstrates great application potential in electrochromic sunglasses and smart windows.

Organic small molecule-based electrochromic materials have garnered significant attention owing to their high transparency, large optical contrast, and facile functionalization. However, several challenges still persist in achieving a truly black switching state and excellent cycling stability. In this work, a highly transparent-to-black electrochromic device (ECD) is developed based on diethyl viologen bis(trifluoromethylsulfonyl)imide ([EV2+](TFSI-)(2)) and N,N,N ',N '-tetrakis(4-methylphenyl)-benzidine (TPD), with potassium hydroquinonesulfonate (H(2)QSK) employed as a redox mediator. Theoretical calculation demonstrates that the introduction of H(2)QSK can promote the reduction kinetics of TPD, and mitigate the interfacial deposition of the oxidized TPD species, thereby significantly enhancing the cycling stability of the device. The fabricated ECD exhibits excellent overall performance with an average optical contrast of 46.3% in the visible region, a switching time of <5 s, and a transmittance retention of 93.8% at 550 nm after 15,000 cycles. In addition, the device achieves a large optical contrast of 37.9% in the near-infrared region. Notably, the optical contrast of the ECD can be tuned by modifying the thickness of the spacer for ECDs. Consequently, a large-area ECD (10.0 cm & times; 10.0 cm) exhibits a notable temperature difference of 5.8 degrees C in a realistic photothermal test, confirming its effective thermal regulation capability. In energy-saving simulations, the ECD achieves an annual energy savings of 89.39 MJ/m(2) compared to Low-E glass. Intriguingly, a patterned electrode was designed and assembled to enable multi-zone independent control of color changes and optical transmittance. This work develops the high-performance transparent-to-black ECD using hydroquinonesulfonate salt as an efficient redox mediator, which holds promising potential for applications in energy-saving windows and smart dimming glasses.

The combination of solid-state gel electrolytes and electrochromic (EC) materials is expected to propel electrochromic display technology toward truly commercial applications. In this paper, a water-soluble viologen derivative dibromo-1, 1 '-diethyl-4,4 '-bipyridine salt (EtVBr2) was firstly synthesized. Then, using EtVBr2 as the active component, deionized water as a solvent, LiBF4 as an electrolyte, and acrylamide (AAm) as a monomer, a PAAm-based hydrogel electrolyte with electrochromic properties was prepared via thermal polymerization. The electrochromic hydrogel exhibited excellent optical transmittance (91.0 %) and ionic conductivity (4.41 x 10-3 S cm- 1). A double-layer electrochromic device with a structure of transparent electrode/electrochromic hydrogel was assembled by attaching the electrochromic hydrogel to ITO conductive glass. Operating without any encapsulation, the device is highly transparent at 0 V and deep purple at -0.7 V, with an optical contrast as high as 60.3 % and good cycling stability (retaining 52.1 % of the initial optical contrast after 200 cycles). Compared with other electrochromic hydrogels and conventional "sandwich"-structure EC devices, this electrochromic hydrogel features a simple preparation method. A simple double-layer EC device can be constructed using only a single layer of transparent electrode and a layer of multifunctional hydrogel, which simplifies the device architecture by reducing the number of functional layers, potentially lowering fabrication complexity and cost compared to traditional multi-layer devices to enter people's daily lives.

To overcome the structural and conductive degradation from silicon anodes' large volume expansion, this study developed a dynamic disulfide (S-S) crosslinked polyacrylic acid (PAA) binder that forms a stable, elastic network to enhance both electronic and ionic conduction. Under dynamic conditions like shear stress or high temperatures, S-S bonds mitigate mechanical stress from volumetric changes through reversible cleavage and recombination, which preserves physical contact between active materials and facilitates a stable electron transport network for efficient charge transfer. Furthermore, S-S bond cleavage generates sulfur radicals that coordinate with lithium ions to build rapid transport channels, while a reduced glass transition temperature enhances polymer chain mobility, further improving lithium-ion conduction. Electrochemical testing further indicated that the silicon-based anodes employing this binder exhibited excellent cycling performance, maintaining a high-capacity retention rate even after hundreds of cycles at a 0.5C rate. This high-capacity retention rate shows the binder effectively maintains electrical connections and handles volume changes, making it a strong candidate for next-generation lithium-ion batteries.

Electrochromic (EC) military camouflage offers adaptive color changes, lightweight design, intelligence, and low energy consumption. However, challenges like multicolor display for complex environments, integrating flexible and multifunctional devices hinder its development. This study synthesize a solvent-processable viologen-based ionic porous organic polymer nanosheets (p3BDI-TPG) via a schiff base reaction of 1, 1 '-bis(4-aminophenyl)-[4, 4 '-bipyridine]-1, 1 '-diium chloride (BDI) and 2, 4, 6-triformylphloroglucinol (TPG), enabling multicolor displays (orange yellow, modena, army green) at different voltages and a high charge storage capacity of 152.8 F cm(-3). The flexible reflective Zn-based EC device (F-RZECD), flexible transmissive Zn-based EC device 1 (F-TZECD-1), and flexible transmissive Zn-based EC device 2 (F-TZECD-2) are assembled using p3BDI-TPG as EC layer and Zn foil/frame as anode. All devices demonstrate flexibility (0-180 degrees bending), excellent energy storage property, multicolor and patterned displays (27 patterns), rapid switching (<= 3.5 s), self-powered capabilities, and good cycling stability (>3000 cycles). In addition, F-TZECD-2 can display six colors with 216 patterns for superior camouflage. The solution-processable p3BDI-TPG synthesis offers a scalable approach for iPOP film fabrication. The development of three flexible Zn-based EC devices with integrated multicolor displays, energy storage, and self-powering capabilities marks a significant step toward next-generation wearable energy systems and adaptive camouflage technologies.

Viologen-based polymers have attracted considerable attention for electrochromic applications due to their excellent redox reversibility, high coloration efficiency, and structural tunability. Herein, a series of ionic linear polymers (iLPs) and crosslinked polymers (iCPs) based on extended viologen units with different bridging groups (benzothiadiazole, benzene, thiophene, and EDOT) are designed and synthesized by Menschutkin reaction with difunctional and trifunctional monomers. Theoretical calculations reveal that the electron-donating/ withdrawing nature of the bridging unit modulates the energy levels and band gaps (Eg) of the viologen monomers. Spectroelectrochemical analysis indicates that electron-donating/withdrawing groups induce a certain red-shifted absorption of all viologen-based polymers, resulting in the neutral pale yellow films and various colors in their reduced states. Notably, the iLP films exhibit higher energy density (pBEDI: 93.5 Wh/cm3), faster switching time (pBBDI: 1.05 s and 1.53 s), higher coloration efficiency (pBBDI: 157.8 cm2/C) and better cycling stability (pBSNDI: 90% contrast retention after 1000 cycles). In contrast, iCP films achieve deeper coloration (PSNDI: 70.1% of optical contrast), but suffer from slower coloration efficiency (PBDI: 68.2 cm2/C), reduced energy density (PEDI: 68.8 Wh/cm3) and cycling stability (PSNDI: 65% contrast retention after 1000 cycles). Built on iLP films, the zinc-based electrochromic devices (TZECD and RZECD) achieve fast electrochemical responses, high coloration efficiency, and long-term cycling durability, underscoring their strong suitability for practical smart dimming and multi-color display scenarios.

Intelligent energy storage devices, particularly electrochromic supercapacitors (EC-SCs), have garnered considerable interest owing to their rapid charge/discharge kinetics and excellent cycling durability. In this work, we designed and synthesized electrochromic conjugated polymers D1 and D2 featuring cyclopentadithiophene (CPDT) donor and anthraquinone (AQ) dye acceptor via direct arylation polymerization. Both polymers exhibit robust electrochromic performance, including high cycle stability (retaining around 80 % after 1000 cycles) and short response times (1.34 s/1.39 s for D1 and 0.59 s/2.46 s for D2). Under an influence of an applied voltage, their optical states are reversibly modulated, transitioning from warm colors (pink and orange) in the neutral state to purple and a nearly transparent hue in the oxidized state. In addition, the polymers show competitive specific capacitance (1.06 mF cm-2 and 1.23 mF cm-2 at a current density of 0.05 mA cm-2) and sustained charge-discharge cycling stability (retaining around 90 % after 100 cycles), corroborating their bifunctional roles in simultaneous color switching and energy storage. Electrochromic energy storage devices based on anthraquinone dye-based electrochromic conjugated polymer thin films were fabricated and showed obvious color change during the charge-discharge process. Furthermore, the area specific capacitance of each EC-SCs was calculated to be 1.25 mF cm-2 for EC-SC-1, 0.92 mF cm-2 for EC-SC-2 at a current density of 0.05 mA cm-2. This work establishes a viable strategy for achieving efficient electrochromic switching and enhanced energy conversion in EC-SCs, advancing material design principles for multifunctional optoelectrochemical devices.

This study developed intrinsically black polyimide (BPI) films with ultra-wide-spectrum absorption via a synergistic strategy: donor-acceptor-donor (D-A-D) type molecular design and post-treatment optimization. Four DA-D diamine monomers with electron-donating terminals - phenylamine or thienylphenylamine (TPA) and electron-accepting cores - benzothiadiazole or isoindigo (ID) were designed and synthesized. A series of BPI copolymers were then prepared using these diamine monomers, pyromellitic dianhydride, and 4,4 '-oxydianiline. Following that, post-treatment at 450 degrees C induced selective elimination of alkyl side chains and consequently promoted it-it stacking interactions. The polymer incorporating 20 mol% D-A-D monomer (terminal: TPA, core: ID) achieved full absorption in the visible range (400-700 nm), with a total transmittance < 1% and a cut-off wavelength (lambda cut-off) of 712 nm. After thermal treatment at 450 degrees C, the lambda cut-off value increased to 859 nm, and the CIE L*, a*, b* parameters reached as low as 0.01, 0.02, -0.01, respectively. Meanwhile, the thermal stability was significantly improved while maintaining decent mechanical properties, with a modulus of 2.2 GPa, a tensile strength of 195 MPa, and an elongation-at-break of 20%. This work provides an efficient approach to developing high-performance intrinsically BPIs with excellent comprehensive properties.

Electrochromic (EC) technology, particularly dye-based electrochromic systems, has attracted increasing attention owing to its numerous advantages and broad prospects. In this work, two isomeric diketopyrrolopyrrole (DPP) dyes were synthesized and copolymerized with cyclopentadithiophene derivatives (CPDT) to produce two electrochromic polymers pDPP1 and pDPP2 with different linking sites of DPP group. Under an applied electric field, the neutral state of pDPP1 is red, and it becomes transparent upon oxidation. Meanwhile, the neutral state of pDPP2 is orange, while its oxidized state is olive green. Measurements show pDPP1 has a short bleaching time and coloring time of 0.48 s and 0.62 s, while pDPP2 has longer ones of 1.83 s and 1.05 s. In addition, coloration efficiencies of pDPP1 and pDPP2 are estimated to be 231.75 cm2 C-1 and 275.43 cm2 C-1, respectively. The polymer pDPP1 retains 86% of its optical contrast after 800 cycles, significantly higher than that of pDPP2 (67%). Under current density of 0.05 mA cm-2, pDPP1 achieves an areal capacitance of 5.43 mF cm-2. The capacitance retention was about 60% and the Coulombic efficiency remains 95% after 500 cycles. Electrochromic-supercapacitor devices (EC-SC-A) based on pDPP1 films achieved an areal specific capacitance of 6.03 mF cm-2 under the current density of 0.05 mA cm-2, with charging and discharging accompanied by a marked color change from red to transparent. This work achieves efficient electrochromic switching coupled with energy storage based on DPP dyes and provides a new strategy of electrochromi supercapacitor devices from dye material.

A Schiff-base polymer enables flexible zinc-based electrochromic devices that achieve dual-band optical modulation, energy storage and adaptive camouflage.

The development of pure red-to-transmissive electrochromic polymers (ECPs) represents a critical advancement in achieving a comprehensive RGB (red, green and blue) color palette for electrochromic (EC) applications. Herein, a series of monomers based on benzothiazole and diverse electropolymerizable units were synthesized (BZZT, BZZB, and BZZE), and the corresponding ECPs (pBZZT, pBZZB, and pBZZE) were prepared via electropolymerization. Notably, pBZZE film containing 3,4-Ethylenedioxythiophene (EDOT) units can switch between pure red (hue angle, h(degrees)= 359.7 degrees) and high transmissive (color chromaticity, C-ab(& lowast;)= 1.38), which is redder and more transmissive than PDEP. Besides, pBZZE film has a low operating voltage (0.7 V), fast switching times (0.26 s/0.60 s at 535 nm), appropriate optical contrast (25.06% at 535 nm), good coloring efficiency (115.23 cm(2) C-1) and outstanding cycle stability (maintaining 84.84% of the original contrast after 1000 cycles). In addition, the supercapacitor performance of pBZZE was evaluated, revealing an area capacitance (C-a) of 2.29 mF cm(-2), good rate capability and excellent capacitance retention (retaining 65.99% of its initial value after 1000 cycles). In summary, an electrochromic-supercapacitor (ECS) bifunctional material with a pure red-to-transmissive switching capability was successfully developed, paving the way for electrochromic display applications.

Developing adaptive camouflage electrochromic zinc-ion batteries that combine high energy storage density with distinct color switching remains a challenge. This work prepared ion porous organic polymer (iPOP) films (TBDI1, TBDI-2 and TBDI-3) with viologen molecules as Electroactive units via liquid-liquid interfacial polymerization. Among these, TBDI-2 film demonstrates a coral-like loose structure that contributes to outstanding comprehensive properties, including multi-color switching, fast switching time, good cyclic stability and specific capacitance. On this basis, a reflective electrochromic zinc-ion battery TBDI-2//Zn was assembled, which achieves a remarkable specific capacity of 44.8 mAh g- 1 at 0.27 A g- 1 and good rate capability. In addition, the battery is capable of switching between orange-yellow, blue-purple and army green colors, with a rapid switching time (1.16/2.39 s) and high cyclic stability (over 5000 cycles). The multi-color displays not only visually indicate the battery's energy storage status but also facilitate effective adaptive camouflage in various environments.

Achieving adaptive camouflage critically depends on developing high-performance yellow-to-green switchable reflective electrochromic devices (ECDs). In this study, three electrochromic polymers based on triazatruxene (TAT), namely p3CZCT, p3CZCET, and p3CZCDT were obtained via electropolymerization. Incorporating thiophene derivatives into the polymer structure enables precise energy gap modulation, yielding a series of yellow-to-green polymers with fast switching times (similar to 1 s) and robust cyclic stability. Benefitting from the introduction of FeCl3 into the gel electrolyte, the three bilayer-structured ECDs effectively lower the operating voltages (< 1.0 V) with remarkable stability (maintaining over 80% of the original optical contrast after 15,000 cycles) and fast switching times. Notably, the p3CZCDT-ECD maintains its original optical contrast over 15,000 cycles, representing the ultra-high stability among reported organic adaptive camouflage ECDs. To enhance environmental adaptability, TiO2 was incorporated into the gel electrolyte to regulate the reflectance and relative luminance of adaptive camouflage devices. With a 0.7% TiO2 mass ratio, the p3CZCET-ECD demonstrates minimal color difference (Delta E-ab* < 3) from standard military medium green. The reflection spectra switched from yellow to green state for the 6000th cycle substantiate the stability and reliability of the flexible reflective adaptive camouflage p3CZCET-ECD. Furthermore, diverse electropolymerized patterns on electrochromic camouflage nets enhance the continuity and seamlessness of the camouflage design, thereby enhancing adaptability to multiple environments. This work presents a facile strategy to constructing high-performance reflective electrochromic adaptive camouflage devices.

Perovskite quantum dots (QDs) are considered ideal materials for the next generation of light-emitting diodes (LEDs) due to their high color purity and tunable emission. The surface characteristics of QDs, especially the small-sized pure red QDs, significantly impact their optoelectronic performance, with surface defects remaining a major obstacle to achieving high-performance LEDs. Among the QDs synthesized by thermal injection, there are some QDs with poor ligand coverage and low crystallinity, and it is difficult for traditional post-treatment methods to effectively passivate these QDs. Here, we propose a new post-processing strategy using a mixed solution of isopropanol and methyl acetate to dissolve NH4I to selectively screen small-sized QDs. This postprocessing strategy can remove the low crystallinity QDs with poor ligand coverage and effectively passivate the remaining QDs in a halogen-rich environment. As a result of screening out lower-quality QDs, the overall performance of the QDs has been optimized, with the PLQY increasing from 79 % to 95 % and the lifetime improving from 12.7 ns to 13.7 ns. The EQE of devices based on the optimized QDs is 27.15 %, higher than the 19.46 % of the control devices.

Achieving high-realistic electrochromic adaptive camouflage remains a significant technological challenge. In this work, reddish/brown and green camouflage polymers (TTP, TEP, TPP and PBP3P) with excellent electrochromic properties are obtained through terpolymerization. Leveraging the color complementary concept, three dual polymer electrochromic camouflage devices with red-to-green hues are constructed, utilizing TTP/TEP/TPP as the electrochromic (EC) layer, and PBP3P as the ion storage (IS) layer. Notably, the TTP-PBP3P device demonstrated a remarkable 99.94% retention of its initial contrast after 35 000 cycles due to its charge-matching characteristics (the ratio of injected and ejected charges, QOx/QRed ≈ 1), representing the highest stability in current electrochromic camouflage research. By incorporating nylon filter membranes featuring adjustable aperture sizes as transmittance-tunable (TT) layers, the camouflage performance is significantly enhanced. This strategy introduces a novel and robust methodology for achieving ultra-high stability and realistic adaptive camouflage.

High-performance electrochromic supercapacitors require synchronous optimization of optical modulation and energy storage. Herein, a blending polymer film (Pr/Pc) was developed through the physical integration of complementary polymers, which generates a synergistic interaction that enhances charge injection and enables high intrinsic capacitance. Interestingly, the mass of the Pr/Pc film was calculated using mass-absorbance estimation methods based on the Lambert-Beer law and the film achieves a mass specific capacitance of 218.8 F.g(-1) and an area specific capacitance of 10.8 mF.cm(-2). Meanwhile, the Pr/Pc film exhibits reversible black-to-transparent switching with exceptional electrochromic properties. Based on this, an electrochromic supercapacitor prototype device assembled with a Pr/Pc film as the active layer exhibits a mass specific capacitance of 78.8 F.g(-1), a coulombic efficiency of near 100 %, and excellent charging/discharging stability. In addition, the device is capable of switching between black-to-transmissive states with fast switching time and near 100 % optical contrast retention after 500 cycles during charging/discharging.

Electrochromic devices (ECDs) are considered as the next-generation e-paper display and energy storage technology. However, the fabrication of ECDs is hindered by the requirements of the electrolyte, which necessitates transparency, a wide electrochemical window, high ionic conductivity, processability, and stability-all crucial factors in the EC field. At the same time, it is also the focus for an universal method to prepare patterned electrochromic films and devices. In this study, a UV-curable liquid gel electrolyte based on the PEGDA and PMMA which provides the rovide cross-linked skeleton is developed as a straightforward solution to these challenges. The resulting solid electrolyte exhibits high transparency (over 90 %), a wide electrochemical window (-2 to 2 V), a high ionic conductivity (approximately 3.2 x 10-4 S cm-1) and exceptional stretchability with deformation extent exceeding 175 %. Besides, ECDs are successfully fabricated with excellent cycle stability (over 35,000 cycles) even in the absence of an ion storage layer. Surprising is that the patterning of electrolyte could pattern the cling electrochromic polymer film at the same time during the photocuring process. Furthermore, the cured electrolyte films which was flexible enough are also allowed for cutting, machining, rearrangement and combination with patterned EC films, showcasing its potential for efficient, low-cost production of high-quality patterned ECDs. In general, the unique electrolyte not only acts as an important part of the electrolyte layer in the ECDs, but also realizes the patterned display. This breakthrough not only paves the way for the wide application of polymer electrochromic products, but also provides ideas for the design of electrochemical energy storage devices in the future.
