A series of Cu-I photosensitizers was synthesized, characterized, and investigated for photocatalytic H-2 evolution from water. A structure-property correlation was established for their catalytic activity and photophysical properties, which was further elaborated by DFT calculations. A new Cu-I photosensitizer (Cu-TPAPhen) with triphenylamine-substituted phenanthroline ligands showed unprecedentedly high turnover numbers of 19000 when tested in combination with triethylamine as a sacrificial reagent and colloidal Pt as a H-2 evolution catalyst. This work paves the way toward cheap metal-based photosensitizers which can replace noble-metal complexes in photocatalytic systems.
