SYNTHESIS AND PHOTOCONDUCTIVITY STUDY OF PHTHALOCYANINE POLYMERS .5. 4,4'-DIAMINO-DIPHENYL ETHER BRIDGED POLYMERIC SIPC

A novel polymer with quasi-one-dimensional structure of 4,4'-diamino-d iphenyl ether bridged polymeric silicon phthalocyanine (I) is synthesi zed by the condensation polymerization of 4,4'-diamino-diphenyl ether (DDE) monomer and dichloride silicon phthalocyanine (Cl(2)SiPc) monome r. The structure of the polymer (I) is identified by IR subtraction an d UV/VIS spectroscopy and elemental analysis. The photoconductivity of the polymer I with quasi-one-dimensional structure is better than tha t of not only the parent Cl(2)SiPc reactant, but also other polymeric phthalocyanines without one-dimensional structures, and showing one-di mensional effect of molecular structure.
