Electrochemical Water Oxidation Mechanisms Involving Macrocyclic Copper(II) Complexes: Ligand Ring Size Effects on Catalytic Cycles

open access: yesChemPhysChem, EarlyView.
The ring size of the ligand strongly influences electronic properties, steric effects, and coordination modes of key intermediates. Both catalysts show similar energy barriers for OO bond formation, but [Cu(12‐TMC)]2+ exhibits more complex mechanisms due to ligand reorganization.
