Organic conjugated polymers and oligomers have been used as the active semiconducting layer in various organic-based thin film devices such as solid state laser materials, organic transistors, light emitting diodes, photodiodes, and electrode active materials. A series of conjugated polymers functionalized with different ruthenium polypyridine metal complexes were synthesized by the palladium catalyzed reaction. Two conjugated polymer systems have been studied: (1) poly(phenylenevinylene) with bis(2,2{prime}:6{prime},2{double_prime}-terpyridine)ruthenium (II) on the mainchain and (2) quinoxaline based polymers with tris(2,2{prime}-bipyridine) ruthenium (II). The ruthenium polypyridine complexes exhibit a long-lived metal to ligand charge transfer excited state which can enhance the photosensitivity of the resulting polymers. Different physical properties such as the photoconductivity and charge mobility in these polymers are also studied.
