Abstract

Novel block copolymers were synthesized in a controlled fashion by nitroxide-mediated radical polymerization starting from a terpyridine-modified alkoxyamine. An important feature for controlling the efficiency of the polymerization is the presence of excess nitroxide, responsible for the initial rate of deactivation, which eventually leads to a decrease of the polydispersity indices of the desired block copolymer. The materials obtained were characterized by means of 1H NMR, UV-vis spectroscopy, and GPC. The complexation of the terpyridine ligands resulted in the formation of A-B-[Ru]-C, A-B-[Ru]-B-A, and A-B-[Fe]-B-A metallo-supramolecular block copolymers. -© 2006 WILEY-VCH Verlag GmbH & Co. KGaA
