PHOTOSENSITIVE POLYMERS BASED ON BIS(SALICYLIDENE)ETHYLENEDIAMINE COMPLEXES OF COPPER(II) AND PALLADIUM(II)

New data have been reported od the photochemical activity of optically transparent electrochromic and conducting polymers obtained from acet onitrile solutions of bis(salicylidene) ethylenediamine complexes of C u(II) and Pd(II) upon anodic polarization of a platinum electrode. The physicochemical properties of these polymers have been compared with those of polymers of the same composition obtained previously from pro pylene carbonate solution. The charge on the metal centers of the oxid ized polymers has been calculated from the chemical shifts of high-ene rgy x-ray lines. The optical absorption spectra of the oxidized and re duced polymers have been recorded. The factors affecting the values of the photoinduced potential Delta E have been. studied.
