PHOTOPHYSICS OF OPTICAL FUNCTIONAL MATERIALS BASED ON BIOPOLYMER COMPLEXES WITH ORGANIC DYES
Research of physical and chemical properties of organic dyes complexes with biopolymers of different nature is an important task in connection with the great potential of such systems in medicine, nanotechnology, molecular electronics, photonics. This paper presents the results of the optical properties of film studies supramolecular structures based on organic dyes and biopolymers (DNA, chitosan), as well as opportunities for application of these materials in optoelectronics. A method for producing an optically uniform film structures on the basis of double-stranded DNA is formed on the principle of «guest - host», in which the dye molecules ( «guest») have high fluorescence ability. Superluminescence pyronine G obtained in such a system. A method for obtaining effective phosphors based system anionic dye - chitosan. The film system sulforhodamine B - chitosan is also obtained the effect of the dye Superluminescence. Experimentally demonstrated the possibility of using DNA-dye film material as a proximity sensor (sensor element) relative humidity. It is shown that the tested optical functional materials based on biopolymer systems - dye can be used as highly efficient phosphors, proximity sensors and other devices in optoelectronics.
