A new thiophene-based monomer; 1,2-bis(thiophen-3-ylmethoxy)benzene (BTMB) has been synthesized and chemical structure of the monomer was characterized. Polymerization of BTMB and characterization of the resulting polymer P(BTMB) were performed. Spectroelectrochemical analysis of the P (BTMB) reflected electronic transitions at 400 nm, 520 nm and similar to 720 nm, corresponding to pi-pi* transition, polaron and bipolaron band formation respectively. Switching ability was evaluated by a kinetic study via measuring the transmittance (%T) at the maximum contrast. Dual type all polymer electrochromic device (ECD) based on P(BTMB) and poly(ethylene dioxythiophene) (PEDOT) was constructed. Spectroelectrochemistry and switching ability of the devices were investigated by UV-vis spectroscopy. (C) 2010 Elsevier Masson SAS. All rights reserved.
