Abstract

Yellow electrochromic polymers (ECPs) are prepared that display a yellow neutral state and a highly transmissive oxidized state. The ECPs are copolymers where a dyad of dioxyhetereocyclic repeating unis alternate with a monad of an aromatic repeating unit. An alternate yellow ECP has an oxidation potential of 450 mV or less and is an alternating copolymer of an acyclic dioxythiophene (AcDOT) or a propylene dioxythiophene (ProDOT) with an aromatic repeating unit that has an electron donating substituent. The yellow ECPs can be processed from solution for electrochromic devices.
