Alkyne functional di- and triblock copolymers have been prepared with the aid of nitroxide-mediated radical, atom transfer radical, and radical addition-fragmentation transfer polymerization. Reaction of these polymers with dicobalt octacarbonyl leads to cobalt-containing block copolymers which are of use for the preparation of microphase-separated bulk copolymers in which spatially segregated domains contain either cobalt atoms or cobalt nanoparticles. The utility of these diblock and triblock copolymer-based composites for the preparation of materials with multiple metallic nanoparticle-containing domains will be discussed.
