Abstract

A conducting polymer of diphenyldithieno[3,2-b;2′,3′-d]thiophene (DPhDTT) was synthesized via potentiodynamic method in dichloromethane (DCM)/acetonitrile (AN) (1:9 (v/v))-NaClO4/LiClO4 (0.1:0.1 M) solvent-electrolyte couple. Characterizations of the resulting homopolymer were performed by cyclic voltammetry (CV), Fourier transform infrared (FTIR) and UV-Vis spectroscopy. Moreover, the spectroelectrochemical and electrochromic properties of the homopolymer films were investigated. Consequently, P(DPhDTT)/PEDOT device was constructed and their characteristics were examined in detail. A potential range of 0.0-2.0 V was found to be suitable for operating the P(DPhDTT)/PEDOT device between yellow and blue colors. The device reveals good open circuit memory and stability.
