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 Sm-1 in vacuo and in air. © 1997 Elsevier Science Ltd.
