Synthesis and Properties of 1,5-Dithio Bridged Polymeric Phthalocyanines

Abstract

Oxa-thio bridged metal-free and metal phthalocyanine polymers were prepared. Metal-free phthalocyanine polymer (H<inf>2</inf>Pc) 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 [NiCl<inf>2</inf>, CuCl, CoCl<inf>2</inf>, Zn(CH<inf>3</inf>CO<inf>2</inf>)<inf>2</inf> or Fe(CO)<inf>5</inf>]. 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.
