Abstract

A novel red to transmissive electrochromic polymer is described. A monomer which consists of EDOT and phenanthrocarbazole units was designed. Upon electrochemical polymerization of this material, a red colored polymer film was formed, which upon oxidation switches to a highly transmissive state. A high optical contrast (51%) and fast switching times (0.65 s and 0.52 s) were achieved, making this polymer an important candidate for electrochromic device and simple display applications. In addition, to best of our knowledge, this is the first example of a phenanthrocarbazole containing electrochromic polymer.
