Broadly Absorbing Black to Transmissive Switching Electrochromic Polymers

Random donor-acceptor conjugated copolymers with broad and even absorption across the visible region exhibit black neutral states and highly transmissive oxidized states. Polymer films show excellent optical contrasts, fast switching times, and long-term redox switching stability. Additionally, the utility of this black-to-transmissive switching polymer in a window-type electrochromic device has been demonstrated.
