Abstract

Electropolymerization of 3,5-bis(4-methoxyphenyl)dithieno[3,2-b;2′, 3′-d]thiophene BMPhDTT, having strong electron-donating methoxy groups, was performed, utilizing potentiodynamic method. The homopolymer was characterized by cyclic voltammetry (CV), Fourier transform infrared (FTIR) and UV-vis spectroscopy. Spectroelectrochemical and electrochromic properties of the homopolymer film were investigated and a PBMPhDTT/PEDOT device was constructed to understand its characteristics in detail. It was revealed that the potential range of 0.0-2.0 V is suitable for operating the device between yellow and blue colors. It indicated a good open circuit memory and stability.
