Inspired by the CuB site in CcO, a molecular CuII complex (1) featuring a mixed pyridine-phenol ligand has been designed and synthesized. Electrocatalytic and chemical oxygen reduction reactions in the presence of 1 demonstrate a 4eā/4H+ reduction of O2. Kinetic analysis reveals distinct reaction mechanisms for the chemical and electrocatalytic pathways and highlights the crucial role of the ligand backbone in the ORR process.
