Abstract A copolymer of 2,2′:5′,2″-terthiophene and 3,4-ethylenedioxypyrrole was synthesized as a new electrochromic polymer and its spectroelectrochemical properties were investigated. This copolymer shows multicolor electrochromism, switching between dark blue, light brown, and orange-red. Three different electrochromic materials were evaluated using the electrochromic copolymer. Double potential step chronoamperometry experiments showed that this copolymer film has good stability, fast… CONTINUE READING
