Cover Story: Molecular copper–water oxidation electrocatalysts have the potential for solar energy conversion in artificial photosynthesis, but ligand modification and its influence on catalysis have seen few systematic studies. A complex of our oxidatively resistant pyalk (2-pyridyl-2-propanoate) ligand with copper(II) catalyzes water oxidation, and we now report a series of analogous copper complexes with electron-donating (methoxy-) and -withdrawing (methoxycarbonyl-) groups at the para-position of the pyalk ligand. Trends in the pKa and redox potential align with first-principle predictions for the electron-withdrawing and -donating groups. While the modified complexes show good activity for water oxidation, lowered faradaic efficiency compared to the parent complex highlights the importance of catalyst stability for effective water oxidation.
