dc.description.abstract | Conjugated polymers exhibiting adjustable color changes under an electric field have been receiving great research interest due to their potential use in electrochromic applications. High-performance electrochromic materials are required to have well-defined donor-acceptor (D-A) units, a low optical bandgap, and fast response time. To fulfill these demands, herein, for the first time, two conducting macromolecules poly-3,8-diaminobenzo [c]cinnoline (P1) and poly-4,7-bis(phenyldiazenyl)benzo[c]cinnoline-3,8-diamine (P2) were successfully fabricated on the ITO substrate via electrochemical polymerization from their corresponding monomers in 0.1 M TBAP/acetonitrile solution. Consequently, two conjugated polymeric films show well-defined azo and amine functional groups, which are responsible for electron-withdrawing and electron-donating, respectively. The optical bandgaps (E-g) of P1 and P2 films were found 1.87 eV and 1.81 eV, respectively. The P1 exhibited a yellowish-brown color in neutral states and reduced states and a dark brown color in oxidized states while the P2 showed an orange color in neutral states, brownish orange color in oxidized states and a dark brown color in reduced states. It has been found that the P1 shows a higher conductivity, shorter switching time and better stability while P2 exhibits advanced the chromic and electron-withdrawing characteristics, which were attributed to the substituted phenyldiazenyl units contacted to the benzo[c]cinnoline (BCC) and lower oxidation potential of P2. This study opens a new avenue into the electrochromic application via the effective electropolymerization of corresponding monomers. | en_US |
