A copolymer of poly(methyl methacrylate) with terpyridine units in the side chains was synthesized utilizing free radical polymerization. The free terpyridine units were complexed with several different terpyridineruthenium mono-complexes, yielding metallo-supramolecular graft copolymers. The materials obtained were characterized by means of NMR and UV-vis spectroscopy as well as GPC. Characterization by thermal analysis revealed distinct differences between these new materials and the initial copolymer.
