Objects of investigations: organic semiconductors, molecular and liquid crystals, thin films, organic dyes, n-paraffines. Methods of investigations: photo- and thermoluminescence; infrared, Raman and fluorescence spectroscopy; differential scanning calorimetry; X-ray analysis; electro-optical measurements. Comprehensive investigations of the charge excitation-transport processes in organic semiconductors and polymeric matrixes activated with metal-organic complexes were performed. A dipole-dipole Ferster mechanism for triplet exciton transport in metal-organic complexes was revealed. The absorption and fluorescence spectra of nanocomposites of molecular chromophores embedded in silica glass with nanoscale porous structure were investigated. It is shown that the changes in photophysical properties of organic molecules embedded in porous silica glass are determined by their inhomogeneous distribution on the porous surfaces and specific solvatation processes. New organic molecules with optimized electronic parameters for nonlinear optical applications were developed. A reversible frequency tuning of the distributed feedback cholesteric liquid crystal laser was obtained under light irradiation with different wavelengths.
