Embodiments of the invention are directed to yellow/orange-to-transmissive conjugated polymers, a method to prepare the yellow/orange conjugated polymers, and an electrochromic and/or electroluminescent device comprising the neutral state yellow/orange conjugated polymers as one of a plurality of primary subtractive colored conjugated polymers. The yellow/orange conjugated polymers show enhanced redox stability and can have a (D2Arz)n structure with a dioxyheterocycle repeating unit or a (DArz)n structure with a dioxythiophene monomer that has at least one substituted carbon α to an oxygen of the monomer; and where the one to three Ar groups have at least one carbon α to the carbon attached to a D unit substituted that has at least 5 atoms in the substituent. The yellow/orange conjugated polymers show enhanced redox stability. The yellow/orange conjugated polymers are prepared by cross-condensation reactions.
A conjugated polymer, comprising a (D2Arz)n fully conjugated polymeric sequence of two donor (D) repeating units with at least one aromatic (Ar) repeating unit provided therebetween,
