Tuning the bandgap of electrochromic polymers is one of the important research topics in electrochromism. To understand clearly the effect of donor unit in donor-acceptor-donor-type polymers, 2,3-bis(4-tert-butylphenyl)-5,8- di(thiophen-2-yl)quinoxaline and 2,3-bis(4-tert-butylphenyl)-5-(2,3- dihydrothieno[3,4-b][1,4]dioxin- 5-yl)-8-(thiophen-2-yl)quinoxaline were synthesized and polymerized potentiodynamically. Their electrochemical and spectroelectrochemical studies were performed, and the results were compared with those of poly(2,3-bis(4-tert-butylphenyl)-5,8-bis(2,3-dihydrothieno[3,4-b] [1,4]dioxin-5-yl)quinoxaline) (Gunbas et al., Adv Mater 2008, 20, 691-695). A blue shift in the polymer π-π* transitions revealed that the bandgap of such polymers with the same acceptor unit is related to the electron density of donor units.
