Spray‐Processable Blue‐to‐Highly Transmissive Switching Polymer Electrochromes via the Donor–Acceptor Approach

Abstract

Spray processable blue electrochromic polymers with strictly alternating “donor-acceptor” copolymers are reported that exhibit saturated blue neutral states, highly transmissive oxidized states, excellent optical contrasts, fast switching times, and long-term redox switching stability. In addition, an alkylester-functionalized analogue is demonstrated, where the solubility of the material thin-film is irreversibly changed while allowing it to retain its electroactivity.
