P-Type polyphenoxazine electroactive polymers

Claim 1

A p-type electroactive polymer which comprises a charged polymer backbone of recurring units of a substituted or unsubstituted phenoxazine and a sufficient concentration of a charge-compensating anionic dopants associated therewith, wherein said polymer backbone is capable of undergoing reversible oxidation to said charged polymer backbone and said substituted phenoxazine contains from 1 to 3 substituents on the carbocyclic ring which links into the polymer backbone and from 1 to 4 substituents on the carbocyclic ring adjacent to the central ring containing the nitrogen atom which links into the polymer backbone wherein the substituents are independently selected from H; alkyl of 1 to 4 carbon atoms; alkoxy of 1 to 4 carbon atoms; an alkylthio of 1 to 4 carbon atoms; a cycloaliphatic group of 5 or 6 carbon atoms; an aryl group of 6 to 10 carbon atoms; an aryl group of 6 to 10 carbon atoms substituted by 1 to 3 alkyl groups of 1 to 4 carbon atoms, alkoxy groups of 1 to 4 carbon atoms, 1 to 3 cyano groups, 1 to 3 halogen atoms, dialkylamino groups of 1 to 4 carbon atoms, an alkylthio of 1 to 4 carbon atoms; and a 5- or 6-membered nitrogen-containing unsaturated heterocyclic group.
