Thermal treatment, spectroscopic analyses, and electrical properties of poly(copper 2,3,9,10,16,17,23,24‐octacyanophthalocyanine)

Thermal treatment of novel poly(copper 2,3,9,10,16,17,23,24‐octacyanophthalocyanine), PCOCP, has been carried out at different temperatures in an inert atmosphere. As polyacrylonitrile, the polymer can be thermally cyclized through the cyano groups to produce semiconductive and conductive materials. Polymeric copper octacyanophthalocyanine material with a conductivity as high as 5–8 (Ω cm)‐1 was prepared. Weight loss, electrical data, infrared, and photoacoustic results of the thermally treated copper octacyanophthalocyanine polymer are discussed.
