Poly(dimethylsiloxane)-substituted 2,2 ': 6,2 ''-Terpyridines: Synthesis and characterization of new amphiphilic supramolecular diblock copolymers

Terpyridine-modified hydrophobic poly(dimethylsiloxane) and hydrophilic poly(ethylene oxide) were combined to new metallo-supramolecular AB-diblock copolymers by utilizing Ru(II) ions. The polymers were synthesized by hydrosilylation of heteroleptic allyloxy-functionalized Ru(II) complexes. The amphiphilic AB-diblock copolymers were used to prepare micelles in an aqueous environment, which were subsequently characterized by dynamic light scattering and cryogenic transmission electron microscopy.
