Chirality-driven metallo-copolymer formation
Résumé
The combination of two heterochiral bisoxazoline ligands at one metal centre has been successfully used to generate coordination copolymers. The addition of a Zn metal ion to a monomer that has enantiopure C 2-symmetric bisoxazoline units placed at either end does not favour the formation of self-aggregates. On the other hand, the use of a racemic mixture of the same ligand leads to the formation of a metallopolymeric assembly. The combination of two heterochiral bisoxazoline ligands at one metal centre has been successfully used to generate alternating coordination copolymers. Copyright © 2012 WILEY-VCH Verlag GmbH & Co.
