Crystalline mixed-valence copper supramolecular isomers for electroreduction of CO2 to hydrocarbons

Supramolecular isomers show that the structural stability is improved by increasing the dihedral angle. CuL-4 as a catalyst can reduce CO 2 to hydrocarbons (FE = 85.02%), and explore the role of mixed-valence copper sites in CO 2 electroreduction.
