Engineering with Metallo-Supramolecular Polymers: Linear Coordination Polymers and Networks

Schmatloch, Stefan; Schubert, Ulrich S.

Abstract:

Here we demonstrate the synthesis of telechelics with different spacer units and different numbers of metal-complexing units, like -methoxy--(2,2:6,2-terpyrid-4-yl)-poly(ethylenoxide)78 (1), bis(2,2:6,2-terpyrid-4-yl) di(ethylene glycol) (2), bis(2,2:6,2-terpyrid-4-yl)-poly(ethylene oxide)180 (3) and tris[(2,2:6,2-terpyrid-4-yl)-oligo (ethylenoxy-)3.33]glycerin (4) utilizing 4-chloro-2,2:6,2-terpyridine. The complexation behaviour of a variety of metal-salts towards the telechelics was studied and different supramolecular architectures were investigated, such as symmetric polymeric complexes and linear coordination polymers. Furthermore, attempts have been undertaken to prepare metallo-supramolecular cross-linked systems.
