Abstract

A novel conjugated alternating copolymer (PCzDBSe) based on N-9′-heptadecanyl-2, 7- carbazole and 5, 5-(4′, 7′-di-2-thienyl-2′, 1′, 3′-benzoselenadiazole) was synthesized by Suzuki polycondensation. The polymer reveals excellent thermal stabilities with the decomposition temperature (5% weight loss) of 390° C and the glass-transition temperature of 140° C. The absorption peaks of the polymer are located at 412 and ...
