Functionalized oligomers and copolymers with metal complexing segments: a simple and high yield entry towards 2,2′:6′,2″-terpyridine monofunctionalized telechelics

4′-Chloro-2,2′:6′,2″-terpyridine was reacted in a high yield Williamson type reaction with α-hydroxy-ω-carboxy-functionalized poly(ethylen-oxide) to obtain monoterpyridine terminated telechelics. The completeness of the functionalization was proven by NMR, GPC and MALDI-TOF-MS investigations. Addition of transition metal ions resulted in the formation of the corresponding octahedral terpyridine metal complexes and resulted in the formation of metallo-supramolecular dimers.
