LM Litvinenko of the National Academy of Sciences of Ukraine popup.description2  Objects of research: electronically active conjugated and functionalized oligomeric and polymeric systems based on carbazole, thiophene and fluorene. Objective: synthesis and study of patterns of structure - photophysical and electrochemical properties of new conjugated oligomers and polymers, promising for use in molecular and optoelectronics. Methods: cyclic voltammetry, thermogravimetric analysis, spectroscopy absorption and photoluminescence, IR, NMR and Raman spectroscopy. The scientific significance of the work is that based on the analysis of patterns of structure - chemical and photophysical properties for a series of new oligomeric halogen-containing conjugate systems based on carbazole identified structural factors that increase photoconductivity and holographic sensitivity of film polymer composites based on them. The practical significance of the study - synthesized new conjugate functionalized oligomers and polymers that can be used in molecular and optoelectronics to create LEDs, organic lasers, bioprobes, holographic recording media, photovoltaic cells.
