Direct preparation of electroactive polymers on electrodes and their use in electrochromic devices†
Abstract
Thermal polymerization of electroactive thin films using an aminobisthiophene vinylene monomer was done directly on electrodes. The resulting films reversibly switched colors in the visible-to-NIR regions, contingent on the monomers used for polymerization. Working transmissive electrochromic devices were fabricated using the electrode immobilized electroactive polymers. The devices exhibited reversible color changes with a moderate 150 duty cycle.
