1. A conjugated polymer, comprising a fully conjugated polymeric sequence of at least two alternating triads comprising:

  • a first repeating unit selected from dioxythiophene, dioxyfuran, dioxypyrrole, dioxyselenophene, or any combination thereof; and

    a second repeating unit selected from an aromatic molecule, thiophene, furan, pyrrole, selenophene, or any combination thereof, wherein the conjugated polymer is yellow in its neutral state and having an absorption maximum between 300 and 500 nm that upon oxidation is transmissive between 400-750 nm.
