Syntheses of structurally uniform polymeric phthalocyanines

Abstract

Very few papers describe the synthesis of structurally uniform polymeric phthalocyanines. Owing to their insolubility, it is difficult to get information on the structural uniformity, kind of end groups and molecular weight. The reaction conditions are severe to get well-defined polymeric phthalocyanines. In this paper, four methods are described to get pure polymeric phthalocyanines as powders by bulk or solution reactions and as thin films or coatings on carriers.
