Electrochemically synthesized poly(1-co-EDOT) based on the azo dye has a well-defined and reversible redox couple (0.37 V vs. Ag/AgCl) with good cycle stability. The copolymer film exhibits high conductivity (13 S/cm) as well as electrochromic behavior (magenta when neutralized and transmissive sky blue when oxidized). Furthermore, electro-optically active copolymer film has a low band gap of 1.79 eV with a pi-pi* transition at 555 nm.eninfo:eu-repo/semantics/openAccessConducting polymerscopolymersdithienylpyrroleazobenzeneEDOTArticle33675976710.3906/kim-0902-21Q3WOS:0002723573000042-s2.0-7764911543094162Q3
