Green to transmissive soluble electrochromic polymers

摘要

Green to transmissive soluble electrochromic polymers are conjugated polymers having a plurality of repeating units where repeating units are a plurality of substituted dioxyheterocycle based donor groups coupled to an acceptor group. The conjugated polymer absorbs radiation within a first band of the visible spectrum and a second band of the visible spectrum when in a neutral state resulting in a green color and is transmissive when in an oxidized state. The polymers are soluble allowing processing of films and coatings from solution.
