SYNTHESIS AND PROPERTIES OF PHOTOACTIVE AND ELECTROACTIVE POLYMERS BASED ON TRANSITION-METAL COMPLEXES

We report the photochemical and electrochemical activity of metallopol ymers (organized molecular systems) based on transition metal complexe s with 5-chloro-1,10-phenanthroline and Schiff bases. These polymers a re redox conductive, optically transparent and electrochromic. Their c alculated charge diffusion coefficients (D-ct) are in the range 10(-11 )-10(-10) cm(2) s(-1). The optimal conditions of polymer formation as a function of the potential, their time of growth and their spectral c haracteristics (absorption) were registered. In the solid polymer matr ix, the activation barrier does not exceed 30 kJ mol (-1) for the bimo lecular electron transfer reactions. The photopotential of the electro de, coated with a redox film, reached magnitudes of 70-450 mV dependin g on the polymer.
