Photovoltaic properties of supramolecular assemblies obtained by incorporation of Preysler's type polyoxometalate in a polycationic copolymer of porphyrin

Poly-zinc-octaethylporphyrin/P5W30 films have been synthesis through incorporation of Preyssler-type polyoxometalate ions, namely [NaP5W30O110]14− (P5W30) into zinc octaethylporphyrin/viologen-based polymers (poly-ZnOEP) films. The electrochemical impedance spectroscopy as well as the photovoltaic performances under visible light irradiation have also been investigated.206
