A unique processable green polymer with a transmissive oxidized state for realization of potential RGB-based electrochromic device applications

Realization of commercial RGB-based polymer electrochromic-device applications can only be achieved by processable materials that possess three complementary colors in the reduced state and are transparent in the oxidized state. This report highlights the synthesis of the first processable green polymer with a transmissive oxidized state. The polymer revealed superior optical contrast in the visible region with fast switching times and robust stability. Hence, this material is the outstanding candidate for completion of RGB color space through commercial polymeric electrochromics.
