Selective Four-Electron Reduction of Dioxygen by a Mononuclear Copper Complex Supported by a Pentadentate Polypyridylalkylamine Ligand

Key Points

• Investigate a novel copper complex for efficient four-electron reduction of dioxygen to water.
• Synthesis of a mononuclear copper complex.
• Utilization of a pentadentate polypyridylalkylamine ligand.
• Evaluation of catalytic performance in the oxygen reduction reaction.
• The copper complex demonstrated a selective four-electron reduction of O2.
• This reaction efficiently converted O2 to H2O.
• Performance exceeded traditional Cu–tris(2-pyridylmethyl)amine systems.
