Polypyrrole films doped with ABTS {2,2‘-azinobis(3-ethylbenzothiazoline-6-sulfonate)} show multicolor electrochromism: the anodic coloration from brown at 0.0 V to greenish blue at 0.8 V due to oxidation of ABTS to its radical; and the cathodic coloration to yellow (−1.0 V) based on the reduction of polypyrrole itself.
