Patent ID: 8308978

Claim:
A composition comprising a polymer comprising repeat units selected from the group consisting of: where R is independently selected from H, D, F, alkoxy, aryloxy, alkyl, aryl, alkyl ketone, aryl ketone, alkylester, arylester, amide, carboxylic acid, fluoroalkyl, fluoroaryl, polyalkyleneoxy, any two of the R groups may be bridging, A and B are independently selected from the group consisting of —O—, —S—, —NR 1 —, and —CR 1 R 2 —, —CR 1 R 2 CR 3 R 4 —, —N═CR 1 —, —CR 1 ═CR 2 —, —N═N—, and —(CO)—, where R 1 -R 4 are H, D, F, alkyl, aryl, alkyleneoxy, polyalkyleneoxy, alkoxy, aryloxy, fluoroalkyl, and fluoroaryl, two of the R 1 -R 4 groups may be bridging within the repeat unit, m is 0-2, n is 0-3, o is 0-4, p is 0-5, q is 0-6, and E is selected from the group consisting of O, NH, and S; and one or more luminescent metal ions or luminescent metal ion complexes, wherein the excited state of the polymer is at a higher energy level than the excited state of the luminescent metal ions or luminescent metal ion complexes.
