The properties of nanofibers (NFs), such as their aspect ratio, tensile strength, porosity, and the ability to combine organic-inorganic materials, make them important in biomedical applications, electronics, and optics. Several methods for the production of these NFs are still being developed, and electroblowing is one such method. This method allows for high yields in very short times, while also saving energy through the use of airflow. By utilizing the advantages of this method, metal oxide nanoparticle ()NFs will have the potential to be used in many applications, stimulating the production of new materials. In this study, poly(epsilon-caprolactone) (PCL)/MeONP NFs were produced via electroblowing using PCL obtained by deposition, along with copper oxide (CuO), iron oxide (FeOx), and manganese oxide (MnO) NPs. These fibers were characterized by FTIR, UV-Vis spectroscopy, XRD, TGA, DTG, DMA, SEM, and EDS analyses. These PCL/MeONP NFs were observed to have antioxidant properties by the 2,2 '-Azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) assay, and the highest antioxidant activity of 54.32 mu g TE/mg was obtained from PCL/CuO NFs. The estimated optical band gap of these nanofibers was calculated to be 2.41-2.82 eV. PCL and MeONPs are widely used as biomaterials, and the electroblown PCL/MeONP NFs presented for the first time in this study have the potential to be used as biomaterials in many biomedical applications.

Homopolymer and copolymer prepared from E2-NBT, containing 3,4-ethylenedioxythiophene as donor and nonylbithiazole as acceptor units, were used for the supercapacitor application. Homopolymer, PE2-NBT and copolymer with E (coPE2-NBT/E) were electropolymerized on ITO. Redox and capacitive behaviors of PE2-NBT and (coPE2-NBT/E) were performed by cyclic voltammetry, electrochemical impedance spectroscopy and galvanostatic charging-discharging. Furthermore, these polymer coatings were modified by the Au nanoparticles to obtain PE2-NBT/Au and coPE2-NBT/E/Au and their conductivity and stability were enhanced. coPE2-NBT/E/Au showed a specific capacitance of 4.9 mF cm-2 at a current density of 0.02 mA cm-2, has a satisfactory area-specific capacitance among Donor-Acceptor-Donor type conjugated polymer films. Upon evaluating the capacity retention performance of the coPE2-NBT/E/Au supercapacitor device, it demonstrated stability for up to 10,000 cycles, with a retention value of 77 %. The combination of three supercapacitor devices can power a 2.0 V, 0.04 W red LED light for 15 s. This study demonstrates that PE2-NBT is a promising candidate for Donor-Acceptor-Donor structured polymers in smart micro-supercapacitor device applications.

Sustainable energy storage materials are of increasing importance for new energy technologies to produce more intelligent, lighter, thinner and multifunctional power systems. In this study, copolymers of N-(4-(4-thieno[3,2-b] thiophene-3-ylphenyl)phenyl)-N-phenylbenzenamine (TTpTPA) and 3,4-ethylenedioxythiophene (EDOT) were synthesized electrochemically starting from different molar ratios of TTpTPA(T) and EDOT(E) (nT:nE). The copolymers obtained on the ITO surface, i.e. P(T10-1E), P(T5-1E), P(T5-2E), P(T1-1E), were directly used to design electrochromic energy storage devices (ECESDs). Electrochemical characterizations suggested that the copolymerization improved the capacitances of PTTpTPA and PEDOT up to the highest value of 21 mF cm- 2 with the copolymer P(T1-1E). It exhibited a color change from purple to blue during charging and discharging processes. Additionally, P(T5-2E) displayed a remarkable multicolor change as a color cartel, i.e. red, yellow, green, gray and blue, during the oxidation with a high color efficiency of 161 cm2C-1. Finally, the flexible symmetric device prototype of P(T1-1E) possessed a good practical application for next generation energy storage devices with its high energy and high-power densities.

The purpose of this study was the polymerization of carbazole (Cz), pyrrole (Py) and copolymerization of them onto polyester (PES) textile with chemical oxidative method by using FeCl3. First, in order to determine the optimum conditions, the effect of polymerization steps, the immersion order of the PES to the oxidant and monomer solutions, time, monomer, oxidant, and surfactant concentrations and types on the conductivities of PES/PCz composite were investigated and at this conditions, conductive composite, PES/P[Py-co-Cz] was obtained. The highest conductivities were obtained as 12.4 mS/cm and 9.0 mS/cm for PES/PCz and PES/P[Py-co-Cz], respectively. Further characterization of PES/P[Py-co-Cz] was performed by conductivity, FTIR, scanning electron microscopy (SEM), and dynamic mechanical analysis (DMA) measurements, and results were compared with PES/PCz and also PES/PPy. The presence of Py and Cz in the same polymer chain created synergy and improved the conductivity and mechanical properties of the composite.

Capacitive and electrochromic behaviors of electrodeposited poly{4,4 '-[2,6-bis(2,3-dihydrothieno[3,4-b][1,4]dioxin-5-yl) dithieno[3,2-b:2 ',3 '-d]thiophene-3,5-diyl] dibenzonitrile}, P[E-CNDTT-E], are reported. The morphological, structural, and electrochemical properties of the polymer are determined by atomic force microscopy, Fourier transform infrared, cyclic voltammetry, spectroelectrochemical measurements, electrochemical impedance spectroscopy, and galvanostatic charging/discharging measurements. Theoretical calculations support the planarity of the structure through OS interactions, which allow the polymer to have a low band gap of 1.43 eV. P[E-CNDTT-E] has a high capacitance of 223 F g(-1) at the current density of 1 A g(-1) and displays a color change from purple to gray with an optical contrast of 30% and a coloration efficiency of 450 cm(2) C-1 upon applying cathodic potential. The solid-state supercapacitor is constructed, which has a high specific capacitance of 63 F g(-1) and a significant energy density of 6.5 W h kg(-1). Additionally, the device retains 90% of its capacitance after 8000 cycles.

The novel monomer, 4‐(2‐(4‐(bis(4‐(thiophen‐2‐yl)phenyl)amino)phenyl)‐5‐(thiophen‐2‐yl)thieno[3,2‐b]thiophen‐3‐yl)benzonitrile, is synthesized by applying Suzuki coupling reaction and electropolymerized directly onto indium tin oxide coated glass electrode surface to obtain a conjugated microporous polymer of [Th3CNTT–TPA] (P[Th3CNTT–TPA]). The morphology and structure of the polymer film are characterized by atomic force microscopy, Fourier transform infrared, and UV–visible spectroscopies. Electrochemical properties are studied using cyclic voltammetry, electrochemical impedance spectroscopy, galvanostatic charge–discharge, and chronoamperometric measurements. Its gravimetric capacity and capacitance values are measured to be 65 and 235 F g−1 at a current density of 3 A g−1, respectively. It shows high energy and power densities of 65 and 32.5 kWh kg−1, respectively, and exhibits high coloration efficiency of 513 C−1 cm2 in visible region, switching between yellow and grey colors. Three different electrochromic–supercapacitor devices, that is, one symmetrical (energy storage device (ESD)1) and two asymmetrical, using poly(3,4‐ethylendioxythiophen) (ESD2) and poly(3,4‐propylenedioxypyrrole) (ESD3) as counter electrodes, are fabricated. The asymmetrical device, ESD3, demonstrats better capacity and stability. Regarding the cyclic stability and electrochromic‐energy‐storage properties, P[Th3CNTT–TPA] can be considered as a good candidate for multifunctional applications.

This study was carried out with the aim of obtaining polycarbazole (PCz) with solid-state polymerization by using ultrasound and pressure assisted methods. For ultrasound-assisted method (U), first, the optimum carbazole (Cz) and cerium ammonium nitrate (CAN) amounts, polymerization time, ultrasound application conditions were determined and then the polymers that are called "PCz-U#" were characterized by using scanning electron microscope (SEM), fourier transform infrared spectroscopy (FT-IR), thermal gravimetric analysis (TGA), transmission electron microscobe (TEM), X-ray diffraction (XRD) and four-point prop conductivity measurements. The effect of the applied pressing time during preparation of pellet on the conductivity of PCz-U was also investigated. Pressure-assisted polymerization (P) was carried out at these optimum conditions and the resulting polymer was called "PCz-P#".In order to understand the advantage of the ultrasound and pressure assisted methods, conventional polymerization in a solution was also performed at the optimum concentrations of Cz and CAN and the properties of PCz's obtained from three different methods were compared. The conductivities of PCz's obtained in a very short time such as one minute with the ultrasound and pressure assisted methods are at the same level as the conductivity of the polymer (similar to 10(-4) S/cm) obtained by the solution method in 20 minutes using 16 and 35.6 times higher amounds of Cz and CAN, respectively. With this study, two new methods for PCz synthesis have been proposed, which are suitable for VOC limitation as no solvent is used in and environmentally friendly because less chemicals are used.

A series of indole (In) and carbazole (Cz) derivative monomers have been synthesized, such as 4-[3-carbazolyl] indole (4In-3Cz), 5-[3-carbazolyl] indole (5In-3Cz), 6-[3-carbazolyl] indole (6In-3Cz), 7-[3-carbazolyl] indole (7In-3Cz). The comonomers synthesized by Stille coupling reaction were characterized by 1H-NMR and elemental analysis. Potentiodynamic method was used for electropolymerization of comonomers, Indole, Cz, and the mixture of In and Cz. Electrochemical activities of resulting P[4In-3Cz], P[5In-3Cz], P[6In-3Cz], P[7In-3Cz], polyindole (PIn), polycarbazole (PCz) and P[In-co-Cz] films were investigated comparatively by CV at different scan rates, electrochemical impedance spectroscopy (EIS) and spectroelectrochemical measurements. The ionization potentials, Ip, specific capacitance, Csp, and optical band gap, Eg, of copolymers were obtained from these measurements. In order to gain some preliminary information on the structure of the copolymers, DFT analysis was performed and dimers and tetramers were optimized.Results suggested that, in order to obtain an In-Cz copolymer with low oxidation potential and band gap, indole ring should be substituted through 5 position to the 3 position of Cz. If high specific capacitance value or high conductivity are desired, P[4In-3Cz] and P[6In-3Cz] are the best copolymers, respectively.

Conductive polymers are considered to be promising material for energy storage applications. Herein, a microporous hybrid energy storage material made of triphenylamine and dithienothiophene, having smart function charge property controlled by color change, is reported. Its polymer film having orange color switched to blue when a voltage is applied to charge the polymer film by oxidation. The film was obtained by potantiodynamic method, and its polymerization mechanism was explained using density functional theory (DFT) calculations. The hybrid energy storage material showed a high specific capacity of 54 mA h g(-1), a high capacitance of 242F g(-1) at 0.5 A g(-1) and a high energy density of 43 W h kg(-1) at current density of 10 A g(-1). Symmetric energy storage device worked at a high voltage (3 V) and lit a red lamp for several seconds. Its combined electrochromic, high optical contrast of 60% and energy storage properties make the microporous polymer an efficient candidate for smart electronic applications, where energy capacity is monitored by simple visual color change.

In this study, single-side polypyrrole (PPy) coated conductive stretchable polyurethane (PU) / PPy composite films were synthesized by chemical oxidative method in the acetonitrile (ACN)/H2O interface as a new alternative to two-side coated PU films which have already reported in the literature. One surface of the PU film was contacted with aqueous Py solution and the other surface with cerium ammonium nitrate (CAN) solution in ACN, so that only one surface of the film was coated with PPy and the resulting composite was named PU/PPy (PUP). This composite was characterized by four-point probe conductivity measurement, Fourier-transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), scanning electron microscopy (SEM) measurements, and mechanical testing. The thickness of PPy coating was determined as 16 μm, by using polarized microscope imagines of crosssection of film. Tg value of the composite was obtained as -60.38 °C and the highest conductivity of PPy coated side of PU was obtained as 3.5 × 10-4 S cm-1, while the back side of PU film was still insulator.

Energy storage materials, having multifunctional properties, are particularly important for the development of intelligent power systems. In this study, conjugated monomers 4',4'-(dithieno[3,2-b:2',3'-d]thiophene-3,5-diyl)bis(N,N-diphenyl-[1,1'-biphenyl]-4-amine) (DTTpTPA, D) and 3,4-ethylenedioxythiophene (EDOT, E) were electrocopolymerized on ITO surface in different mole ratios. The copolymer films were investigated in terms of energy storage, electrochromic properties and surface morphology. Inclusion of EDOT units into the polymer chain made a significant impact on the energy storage and electrochromic properties of the resultant copolymers. The P(D1-1E) film, which was obtained at a mole ratio of n(D)/n(E) = 1/1, showed the best capacitance value of 22 mF cm(-2). All the copolymers displayed a wide range of color change during their redox processes. The best coloration efficiency value of 196 C-1 cm(2) was obtained with P(D10-1E) film, having multi-electrochromic property of red, green, gray and blue colors. A symmetric solid-state energy storage device of P (D1-1E) exhibited a capacitance of 6.58 mF cm(-2) with high energy and high-power density, which proved that P(D1-1E) is a good candidate for energy storage applications.

Silicon (Si)-based anodes have limited application in lithium ion batteries (LIBs) due to the loss of contact with current collector because of large volume change during lithiation and delithiation processes. In this study, pyrrole (Py) was polymerized chemically by cerium ammonium nitrate (CAN) and conductive colloidal polypyrrole (Col-PPy) was obtained in one step in N,N '-dimethylformamide (DMF). To overcome problems during the volume change, Col-PPy was then used as polymeric binder with Si nanoparticle (SiNP) in Si-anode and it called as "Col-PPy/SiNP." In order to improve the cyclability and capacity of Si-anodes, Col-PPy solution was used also together with polyvinylidenefluoride (PVDF) and polyvinylpyrrolidone (PVP). These Si-anodes were further analyzed with cycle tests and combined cycle tests at different rates (C-rate) in half cells and scanning electron microscopy images of electrodes were taken before and after cycling. All results suggested that as an anode for LIB, Col-PPy/SiNP exhibited high reversible capacity (2617 mAh/g at C/10 [0.42 A/g]) and good cycling performance (reversible capacity of 1400 mAh/g after 189 cycles at C/3 [1.4 A/g]).

This study aimed at synthesizing hydrogels to simulate opaque breast tissue (BT) and coloured cancerous tissues (CT) at different densities of the designed phantom to improve the biopsy-related skills along with ultrasonography. Both tissues are tear-resistant and therefore, the phantom can be trained multiple times in order to lower the price and improve the eye-hand coordination of users. For this purpose, self-healing (SH) polyacrylamide (PAAm) hydrogels (SH hydrogel) obtained by free-radical polymerization of AAm, in the presence of chemical cross-linker, BAAm, physical cross-linker stearyl methacrylate, C18, and ammonium persulfate APS as initiator were used in the design of phantoms. Psyllium was added to the BT to differentiate density and obtain human skin color and it could be distinguished from the CT which was also colored with methyl violet. BT and CTs were characterized with FTIR spectroscopy, mechanical, swelling, and refractive index measurements. Designing phantoms from BT and CT were characterized by ultrasonography, mechanical tests, observation of needle track after biopsy, and stabilization tests to follow the self-healing behaviours of tissues with time. As a result of this study, self-healing, low-cost, and suitable for multi-usage ultrasonographic phantom for needle breast biopsy was designed and cancerous tissue was successfully detected.

By the use of natural fibers contributes to the recycle of agricultural wastes, sustainability and further the resulting composite becomes alternative to the metals. Here, flexible conductive composites were obtained from artichoke(A), banana(B) and luffa(L) stem waste fibers(F) by the in-situ polymerization of 3,4-ethylene dioxythiophene (EDOT), pyrrole, and carbazole in the presence of cerium ammonium nitrate, iron nitrate, and iron chloride. Fibers were coated with the conductive polymers mentioned above by the in-situ chemical(C) polymerization and optimum coating conditions were investigated. Effect of EDOT concentration, oxidant concentration was performed to determine the optimum conditions for AF/PEDOT(C). FT-IR, SEM, thermal analysis supported the formation of composite and from the mechanical measurements, modulus of AF/PEDOT(C) was obtained. The highest conductivity of 12.8 S/cm was obtained from AF/PEDOT(C) composite using FeCl3 as an oxidant. Further polymerization of EDOT by electrochemical(E) method was continued on the AF/PEDOT(C) and the electroactivity of resulting electrochemical composite, AF/PEDOT(C)/PEDOT(E) was characterized accordingly. Detailed characterization showed that to use of this composite as a capacitor, one should use 0.03 M EDOT and 0.9 M FeCl3 for chemical polymerization and then continued by electropolymerization by applying 10 cycles in 0.03 M EDOT. All results showed that AF waste could be converted to the valuable AF/PEDOT(C)/PEDOT(E) conductive composites which is potentially suitable material for several electronic applications as charge storage, biosensor, electronic devices.

Titanium dioxide/phthalocyanine (TiO2/Pc), TiO2/fluor containing phthalocyanine (TiO2/FPc), and TiO2/fluor containing cobalt phthalocyanine (TiO2/FCoPc) had been successfully fabricated by a simple combination of phthalocyanines obtained by in-situ synthesis on the surface of TiO2 nanofibers prepared by electrospinning. Scanning electron microscopy micrographs and X-ray diffraction analysis indicated that the phthalocyanines uniformly immobilized on the surface of TiO2 nanofibers. Photocatalytic activity of TiO2, TiO2/Pc, TiO2/FPc, TiO2/FCoPc nanofibers for methylene blue in water was comparatively investigated firstly by ultraviolet-visible absorption measurements with time, and kinetic parameters were calculated. Results indicated that the obtained TiO2/Pc, TiO2/ FPc and TiO2/FCoPc exhibited high photocatalytic activity for the degradation of methylene blue and TiO2/FCoPc was found the best. It showed similar or higher activities than related studies and can be suggested as a promising candidate for environmental and energy applications.

Liposome surface modifications serve great potential applications of liposomes, for instance, increasing stability, bioactive liposome conjugates, and targeted drug, gene, and image agent delivery. In this study, novel targeted lipopolymers, peptide 18/peptide 563-poly(2-ethyl-2-oxazoline)-dioleoylphosphatidyl-ethanolamine (P18/P563-PEtOx-DOPE), have been demonstrated to be successfully synthesized. The structures of P18/P563-PEtOx-DOPE were confirmed by FT-IR spectroscopy, GPC, and(1)H-NMR. In this strategy, poly(2-ethyl 2-oxazoline)-modified liposomes were firstly constructed with molecular weights of 3,500 and 5,800 Da. Then, we chose PEtOx(5800)-DOPE because it has been obtained better particle size (88.74 +/- 0.6816) according to the DLS results. Then, peptides- and dye-PEtOx lipid-based nanovesicle (LN) were prepared by peptide-18, peptide-563, and 7-mercapto-4-methyl coumarin. Genetic material (pDNA) was encapsulated into the liposomes and evaluated the encapsulation of plasmid DNA with migration by using agarose gel electrophoresis.In vitrocytotoxicity experiment results on prostate cancer and breast cancer cell lines, parallelly with the healthy prostate (PNT1A) and breast (MCF10A) epithelial cell lines, cells showed insignificant toxic effects. Thus, we can suggest a novel PEtOx phospholipid thanks to this article and its integration with ligands, which great potential for gene transfer system.

Syntheses of four monomers (Z-TTpTPE, A-TTpTPE, Z-Th2TTpTPE and A-Th2TTpTPE), possessing thienothiophene (TT) and tetraphenylethylene (TPE) units, were achieved by Suzuki coupling reaction, starting from two isomers of TT, namely, thieno[3,2-b]thiophene (ZIT) and thieno[2,3-b]thiophene (ATT). This is the first report that TPE has been attached on to two analogues of TT, i.e. cross conjugated and conjugated, through phenyl moiety and the properties of the resultant electropolymers were investigated. While the corresponding polymer films, i.e. P[Z-TTpTPE], P[Z-Th2TTpTPE] and P[A-Th2TTpTPE] were obtained, the monomer A-TTpTPE did not form any polymer on the electrode surface. Capacitive and electrochromic properties of the resultant polymers were investigated by electrochemical and in-situspectrophotometric measurements. Electrochemical polymerization mechanism was investigated at DFT level, the results of which suggested that although A-Th2TTpTPE and Z-Th2TTpTPE had enough spin density on their peripheral alpha-carbons, Z-TTpTPE and A-TTpTPE did not. Optical band gaps of P[Z-Th2TTpTPE] and P[A-Th2TTpTPE] were determined to be 1.89 and 2.23 eV. Electrochromic behaviors of the polymers suggested that P[Z-Th2TTpTPE] has promising electrochromic properties with high coloration efficiency of 309 cm(2) C-1. Low frequency capacitance (C-LF) values at different E-DC potentials were calculated. The shape of the capacitance-potential graph was found to be in a good agreement with CV of the polymer films, and the highest capacitance values were obtained at their peak potentials. Electrical equivalent circuits were applied to explain the parameters of each element obtained from the experimental electrochemical impedance spectroscopy (EIS). Energy and power densities were calculated from the galvanostatic charge-discharge (GCD) curves. P[Z-Th2TTpTPE] showed a higher energy density compared to P[A-Th2TTpTPE], possibly due to its reversible redox behavior, porous structure, and good roughness, which was supported by CV and AFM measurements. All results suggested that electronic and optical properties of TT were improved by inclusion of TPE, and further enhancement was achieved by attachment of two thiophene rings to the peripherals of the monomers. All the polymers demonstrated promising properties for electrochromic and charge storage applications. (C) 2021 Elsevier Ltd. All rights reserved.

Synthesis of 3-(4-fluorophenyl)thieno[3,2- b ]thiophene ( FPhTT ) and 3,3’-(4- fluorophenyl)dithieno[3,2- b ;2’,3’- d ]thiophene ( FPhDTT ) were achieved starting from 3-bromothiophene and 3,4-dibromothiophene, respectively. They were electropolymerized and the resulting polymers P[FPhTT] and P[FPhDTT] were characterized by diverse electrochemical methods such as cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), galvanostatic charge-discharge (GCD), electrochemical quartz crystal microbalance (EQCM) and spectroelectrochemical measurements. Mechanism of electropolymerization of the monomers was supported by DFT level calculations. Band gaps of P[FPhTT] and P[FPhDTT] were calculated as 1.63 and 1.77 eV, respectively, from the onset absorptions of the absorption spectra. From EIS measurements, the highest capacitance values of P[FPhTT] and P[FPhDTT] were calculated to be 39.4 and 281.7 Fg 1− , respectively, when the applied potentials were equal to their oxidation peak potentials. Surface characterization of the P[FPhTT] and P[FPhDTT] films on ITO electrodes were performed by atomic force microscope (AFM) and the results suggested that P[FPhDTT] had more porous surface. GCD results indicated that P[FPhDTT] had higher energy density than P[FPhTT] , possibly due to its porous structure. According to the ECD results, P[FPhTT] has more stable optical properties. As a conclusion, P[FPhDTT] might be suggested for energy storage applications while P[FPhTT] could be suitable for electrochromic devices.

Electrochemical polymerizations of thieno[3,2- b ]thiophenes (TT), named PhTTTPA, CH 3 OPhTTTPA and CNPhTTTPA , possessing pH, 4-CH 3 OPh, 4-CNPh and triphenylamine (TPA) units, were performed and their corresponding polymers P[PhTTTPA], P[CH 3 OPhTTTPA] and P[CNPhTTTPA] were obtained, respectively. The polymer films were characterized by cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) and spectroelectrochemical measurements, which suggested that while the presence of strong electron donating TPA unit provided them with better electrochemical reversibility, strong electron withdrawing -CN group lowered the oxidation potential of P[CNPhTTTPA] along with enhancement of its charge storage character.

In this study, electropolymerization of pre-synthesized N,N '-di-[3-[2-(3-thienyl)ethyl] phenyl] perylene-3,4,9,10-bis(dicarboximide) (ThPDITh) was performed on Au button electrode and the properties of the resultant polymer P(ThPDITh) were investigated by electrochemical techniques. Effect of the polymerization charge on the redox behaviors of the polymer film was investigated by cyclic voltammetry (CV) and the polymer film was further characterized by electrochemical impedance spectroscopy (EIS) measurements. Corresponding electrical equivalent circuit was applied to the experimental data to explain the electrochemical phenomenon on the interface of the Au/P(ThPDITh). In order to obtain information on the energy storage properties of P(ThPDITh) as a pseudo-capacitive electrode material, important cell characteristics, such as redox process in anodic and cathodic potential ranges, stability of galvanostatic charge-discharge (GCD) curves, coulombic efficiency, capacitance, energy and power density values were determined. Capacitance values, obtained through different measurements (CV, EIS and GCD) are all in good agreement with each other. All the results suggested that P(ThPDITh) is capable of undergoing multiple reversible redox processes, and a good candidate for improving the capacitance and energy density of electrode material while still offering high power capability.
