CuI/CuII Chiral Homoleptic Complexes: Study of Self‐recognition and Self‐discrimination

Abstract

The formation of ML2 homoleptic copper complexes from bidentate chiral ligands with C2 symmetry, comprising three types of substituents (namely benzyl, indanyl and phenyl groups), was investigated. The formation of homochiral or heterochiral complexes can be influenced by the nature of the substituents and the geometry induced by the oxidation state of the metal. All the complexes were isolated and characterized, in particular in the solid state by X‐ray diffraction studies. In solution, cyclic voltammetry was used to study ligand association and discrimination induced by the CuI/CuII transition.
