Abstract:
The design, synthesis, polymerization and full electrochemical and spectroelectrochemical characterization of a new naphtalendiimide-functionalized PEDOT cross-linked electrochromic material is reported. The polymer shows exceptionally high redox reversibility, almost complete colorlessness in the bleached state and a gray color in the reduced state.
