Abstract

Poly(<i>o</i>-methoxy aromatic amine) and its copolymer PTSA-doped poly(3-ABSA-co-OMAA) were synthesized by both chemical oxidation as well as electrochemical method in the presence of external dopant <i>p</i>-toluenesulfonic acid (PTSA). The synthesis of the homopolymer and copolymer poly(3-ABSA-co-OMAA) was confirmed by FT-IR spectroscopy. <span style="mso-fareast-font-family:Calibri;mso-ansi-language: EN-IN;mso-fareast-language:EN-IN">The growth of the electrochemically synthesized samples has been investigated by cyclic voltammogram and chronoamperometry studies for their applications to the electrochromic devices. Both the samples show switching behaviour. T<span style="mso-fareast-font-family:Calibri;mso-ansi-language:EN-IN;mso-fareast-language: EN-IN">he electrochromic switching stability of both devices has been calculated from switching times between their oxidized and reduced states. It has been observed that ECDs based on o-methoxy aromatic amines are promising candidates for electrochromic devices.
