We report on the polymerization/depolymerization of chiral metallo‐supramolecular assembly by Cu I /Cu II redox change. By combining a monotopic enantiopure ligand with a ditopic ligand of opposite configuration, ML 2 ‐type complexes are generated with chiral self‐recognition or self‐discrimination depending on the oxidation state of copper. In presence of Cu I , the formation of heterochiral complexes is favored, thus generating dinuclear species whereas Cu II 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.
