Electrosyntheses and Electrochromic Properies of a Copoymer Based on 9-(4-Pyrrol-1-Yl-Phenyl)-Carbazole and 3,4-Ethylenedioxythiophene

Abstract:

A copolymer based on 9-(4-pyrrol-1-yl-phenyl)-carbazole(PPC) and 3,4-ethylenedioxythiophene(EDOT) was electrochemically synthesized and characterized. The copolymer film not only presented a stable and well-defined redox process, but also exhibited three different colours(orange, green and greenish blue) under various applied potentials. Maximum optical contrast(△T%) and response time of the film were found to be 31% and 2 s at 1100 nm, respectively.
