Cathodically coloring yellow soluble electrochromic and light emitting polymers
First Claim
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, having an absorption maximum between 300 and 500 nm that upon oxidation is transmissive between 400-750 nm, wherein the conjugated polymeric sequence has the structure;

Abstract
Embodiments of the invention are directed to yellow-to-transmissive conjugated polymers, a method to prepare the yellow conjugated polymers, the use of the yellow conjugated polymers in an electrochromic and/or electroluminescent device comprising neutral state primary subtractive colored conjugated polymers, and a method to prepare the device comprising the yellow conjugated polymer. The yellow conjugated polymers comprise a sequence of dioxythiophene units alternating with aromatic units, thiophene units, furan units, and/or pyrrole units. The yellow conjugated polymers are prepared by cross-condensation reactions. The yellow conjugated polymers can be soluble and preparation of the device involves deposition of the yellow conjugated polymer from solution onto a surface.
