Abstract

MONO- AND POLYHYDROXYPHTALOCYANINE OF ZINC GRAFTED WITH  CARBAZOLIC POLYMERS FOR THE PHOTOSENSIBLE MATERIALS 

In the present scientific work we describes the synthesis of zinc mono- and polyhydroxyphtha- locyanines, which have been grafted to some carbazole copolymers in order to create photosen- sitive materials. From obtained powders thin films, which were characterized with X-ray diffraction (XRD), FTIR and UV-VIS spectroscopies were synthetized. The presence of the phthalocyanine fragment in the polymer-analogues were confirmed by the XRD and FTIR spectra. Solar cells based on zinc mono- and tetra-hydroxyphthalocyanines layers with 0.43 V and 0.41 V open circuit voltage, respectively were prepared. 

Keywords: mono- and polyhydroxyphthalocyanines, carbazolic copolymers, solar cells.
