Abstract
We report on the polymerization/depolymerization of chiral metallo-supramolecular assembly by CuI /CuII redox change. By combining a monotopic enantiopure ligand with a ditopic ligand of opposite configuration, ML2 -type complexes are generated with chiral self-recognition or self-discrimination depending on the oxidation state of copper. In presence of CuI , the formation of heterochiral complexes is favored, thus generating dinuclear species whereas CuII advocates for the formation of homochiral species, namely, a mixture of mononuclear species and metallo-supramolecular polymeric species. Thus, cyclic voltammetry was used to study such a chirality-induced stimulus sensitive polymerization/depolymerization process.
