Abstract
The multicolor electrochromism of 2,2′-Azinobis(3- ethylbenzothiazoline-6-sulfonate) incorporated into conducting polymer as a dopant was analyzed. The redox reaction of ABTS/its radical was reversible with one electron transfer. Energy-dispersive spectroscopy revealed the existence of sulfur that originates only from ABTS. The transmission spectra were obtained with the anodic and cathodic coloration of the ABTS-doped polypyrrole (pPy[ABTS]) in the visible region.
