Studies on the electron structure of low-dimensional organic conductors and its modifications caused by phase transitions (mainly metal-isolator transitions), charge ordering phenomena and charge distribution fluctuations, as well as interactions of electrons with internal vibrations of molecules. Investigations of organic proton conductors: dynamics of protons in hydrogen bonds, coupling of electrons and protons with phonons, nature of phase transitions induced by temperature and pressure. Research on carbon materials, including mainly graphene oxide modified with various molecules, which can be potentially used in optoelectronics and photovoltaics.
Using optical spectroscopy methods (FIR-IR-NIR-Vis range) and Raman scattering spectroscopy, vibrational and electronic spectra of charge transfer salts, proton conductors and modified graphene oxides are studied. In many cases, fluorescence spectra are also measured. Experimental studies are supplemented with calculations using theoretical methods of quantum chemistry (DFT methods).
