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.
