Two new quinoxaline and ethylenedioxythiophene (EDOT) based polymers: poly(5,8-bis(2,3-dihydrothieno[3,4-b][1,4]dioxin-5-yl)-2-(phenyll)-3-ferrocenylquinoxaline) (P1) and poly(5,8-bis(2,3-dihydrothieno[3,4-b][1,4]dioxin-5-yl)-2,3-di(naphthalen-2-yl) quinoxaline) (P2) were synthesized and characterized in terms of their electrochemical and spectroelectrochemical properties. The polymers were both p and n-type dopable. The polymers can be switched between green and transparent states during p-doping/dedoping. They were compared with their previously reported analogues in order to investigate ferrocene pendant group effect on electrochromic characteristics. (C) 2010 Elsevier Ltd. All rights reserved.
