Synthesis of metallo-supramolecular block-copolymers

It was shown that terpyridine-ligands are successfully introduced at the end of hydroxy-terminated polymers. By forming a mono-complex these building blocks can easily be coupled. A supramol. AB-block-copolymer of polyethylene glycol and polystyrene were synthesized. The starting materials were both synthesized by anionic polymn. and end-capped to yield polymers with one hydroxidyl end-group and a narrow polydispersity
