SYNTHESIS AND PHOTOCONDUCTIVITY STUDY OF PHTHALOCYANINE POLYMERS .3. PVK-CUPC(NO2)2

Cu-dinitro-diamine phthalocyanine was synthesized, the corresponding d iazonium salt was reacted with vinylcarbazole (VK), and a novel polyvi nylcarbazole (PVK)-bonded CuPc (NO2)2 (I) Wag synthesized. The chemica l structure of polymer (I) is identified by elemental analysis and IR and UV/VIS spectroscopy. Polymer (I) contains about 21 mol % CuPc(NO2) 2 rings that are covalently bonded to PVK. Polymer (I) shows good phot oconductivity, which is much better than that of the corresponding pht halocyanine monomers. The influence of the interface layer and the cha rge-transportation material on the photoconductivity of polymer (I) is also discussed.
