A new electrochromic polymer poly(2-methyl-3,4-dihydro-2H-thieno[3,4-b][1,4]dioxepine) (PProDOT-as-Me) based on 3,4- propylenedioxythiophene (ProDOT) with asymmetric mono-methyl pendant groups was successfully synthesized through electropolymerization in lithium perchlorate/acetonitrile electrolyte couple. The polymer film displays reversible electrochromic behavior switching between dark blue neutral state (-1V) and transmissive sky blue oxidized state (1V). The electrochemistry, spectroelectrochemistry and electrochromic properties of the polymer film were characterized in details..
