Synthesis and characterization of donor–acceptor type conducting polymers containing benzotriazole acceptor and benzodithiophene donor or s-indacenodithiophene donor

Abstract

Two D–A type copolymers were synthesized and characterized by a series of methods. Both copolymers showed high optical contrasts, fast response time and high coloration efficiency. In summary, they could be candidates for electrochromic applications.
