Abstract: Electrochemistry of a new generation copolymer of N-(2,5-di(thiophen-2-yl)-1H-pyrrol-1-yl)-4-(vinyloxy) benzamide (TPVB) and 3,4-ethylendioxythiophene (EDOT) is presented. In this study, a novel copolymer based upon TPVB and EDOT is successfully synthesized and characterized in dichloromethane (DCM)/tetrabutylammonium hexafluorophosphate (TBP6) solution for different feed ratios of monomers via electrochemical methods. The copolymer film reveals three different colors (pale red color, green, midnight blue) under different potentials and it has good optical contrasts (44% at 555 nm and 75% at 1000 nm) and fast swiching times (1.5 s at 555 nm and 2.0 s at 1000 nm). Satisfactory results implied that the copolymer films (P(TPVB-co-EDOT)) can be used in a wide variety of applications such as electrochromic devices, optical displays. We also describe a proposal for the determination of copolymer composition by means of the optical properties of P(TPVB-co-EDOT).
