- Abstract:
- [Cu(I) {6,69-bis(bromomethyl)-2,29-bipyridine}2](PF6) complexes were used as metallo-supramolecular
initiators for the polymerization of 2-oxazolines resulting in defined polymers with a central 6,69-
disubstituted 2,29-bipyridine unit. The living character of the polymerization was demonstrated with the linear
relationship between the weight-average molecular weight M —
w and the [monomer]/[initiator] ratio as well as
in the synthesis of block copolymers. The metal ions could be removed resulting in uncomplexed polymers
with a free central metal binding unit.
