Synthesis and properties of 1,5-dithio-3-oxa-pentanediyl bridged polymeric phthalocyanines

Abstract

Oxa-thio bridged metal-free and metal phthalocyanine polymers were prepared. Metal-free phthalocyanine polymer (H2Pc) and metal phthalocyanine polymers (Ni, Cu, Co, Zn or Fe) carrying dithio-oxa bridged were synthesized from 3, 3' - 4, 4'-tetracyanodiphenyl-1, 5-dithiopentanyl-oxa-ether and hydroquinone or the corresponding anhydrous metal salts [NiCl2, CuCl, CoCl2, Zn(CH3CO2)(2) or Fe(CO)(5)]. The model phthalocyanine compounds were characterized by IR, UV/VIS and DTA. The electrical conductivities of the phthalocyanines measured as gold sandwiches are about 10(-10)S m(-1) in vacuo and in air. (C) 1997 Elsevier Science Ltd.
