Abstract

The incorporation of amine functionality in the periphery of a synthetic cobaloxime core induces excellent photo-(TON 180) and electrocatalytic H₂ production (TOF 4330 s⁻¹) in aqueous solution. The primary amine group displays a superior influence on the catalysis compared to a secondary amine group with an analogous cobaloxime template.
