Interaction of electromagnetic radiation (250–850 nm, 2.5–15.3 μm, and 11.5–17.1 mm) with the isatin-β-anil (C14H10N2O) films deposited with the aid of flow coating is considered. It is shown that the modification of original structure using N, Br, and F atoms leads to frequency deviations and variations in the amplitude of luminescence and changes of the frequency dependences of the absorption coefficients relative to those of the original isatin-β-anil.

In this work, we analyzed the current-voltage characteristics in the temperature range of the hybrid organic material C24H24N6O3Zn in order to determine the prospects for using this compound as a semiconductor material. The range of temperature measurements was from 270 to 330 K. An electrochemical analysis of the studied coordination compound was carried out, the energies of the HOMO and LUMO levels were calculated. The method of obtaining, microscopy, and also the method of measuring the temperature dependences of the electrical properties of the obtained thin films of these hybrid materials based on zinc complexes are described. A number of fundamental values of the films of this coordination compound have been calculated: the activation energy is  0.88 eV and the mobility of charge carriers is  1.4710-11 cm V-1 s-1.

Рассмотрено взаимодействие электромагнитного излучения 250--850 nm, 2.5-15.3 μm и 11.5-17.1 mm с пленками на основе изатин-beta-анил C14H10N2O, осажденными методом полива из раствора. Показано, что модификация исходной структуры атомами N, Br и F приводит к девиации частоты и изменению амплитуды люминесценции, а также к изменению частотных зависимостей коэффициентов поглощения относительно исходного изатин-beta-анила. Ключевые слова: органические тонкие пленки, электромагнитное излучение, изатин, СВЧ, оптический спектр, люминесценция, рентгенофазовый анализ.

The current-voltage characteristics of hybrid organic materials C48H42N6O2Zn and C54H54N6O2Zn are researched. The method of obtaining, microscopy, as well as the results of infrared spectroscopy and studies of the electrical properties of the obtained thin films of these organic materials based on zinc complexes. The results of calculating the optical band gap are presented. It was found that the resulting thin-film structures have N-shaped current-voltage characteristics.

The results of spectral and luminescent study of zinc and magnesium metal complexes are presented. It is shown that radiation in mixed ligand complexes has the charge transfer character, thereby causing a low oscillator strength, large Stokes shift, and high sensitivity to the environment. These complexes are stable in the solid state, but dissociate in solutions at low concentrations.

New coordination zinc compounds based on 3-methyl-4-formyl-1-phenylpyrazol-5-one acylhydrazones [Zn(L)(CH3COO)Solv] (Solv is H2O (I), Py (II)) are synthesized in order to search for new luminophores demonstrating efficient photoluminescence in the visible range. Complexes I and II are characterized by elemental and thermogravimetric analyses, mass spectrometry, and UV and IR spectroscopy. The structures of two complexes [Zn(L5)(CH3COO)H2O] and [ZnL4(CH3COO)Py] are determined by X-ray structure analysis (CIF files CCDC nos. 1958400 and 1958401, respectively). Complexes I and II demonstrate luminescence in the visible range with a maximum at 414–536 nm and a quantum yield of 9.5–64% depending on the nature of the acyl fragment.

The results of using N-isoamylisatin 4-methylphenylhydrazone to optimize fullerene-based heterostructures have been presented. The technique of obtaining, microscopy, as well as the results of IR spectroscopy and the study of the electrophysical properties of thin films of this hydrazone together with fullerene C60 have been described. The addition of the considered organic matter to fullerene films made it possible to increase the photoconductivity by 2 orders of magnitude compared to C60 films. The obtained thin-film structures have rectifying light-current-voltage characteristics.

The present article reports on the syntheses, crystal structures and luminescence properties of three solvate forms of a zinc(II) complex containing 4-{(E)-[(2-fluorophenyl)imino]methyl}-5-methyl-2-phenyl-2,4-dihydro-3H-pyrazol-3-one (HL). The reaction of zinc(II)acetate with the HL ligand in ethanol and acetonitrile led to the formation of two solvate analogues [Zn(L)2]·Solv (Solv – ethanol (1) and acetonitrile (2)). The properties of the [Zn(L)2]·Solv complexes were investigated by UV–Vis absorption and fluorescence emission spectroscopy, and the density functional theory calculations. Bader’s topological analysis was performed to investigate the electronic peculiarities of Zn(II) polyhedra and non-covalent interactions within crystal packing of studied solvates.
