mononuclear compounds. These complexes were tested as PSs with regard to their capacity to reduce water in the photocatalytic system for hydrogen production together with a series of water reduction catalysts and triethanolamine (TEOA) as a sacrificial electron donor. Turnover numbers up to 3780 for the dinuclear iridium complex P1 and 1020 for the mononuclear iridium compound P3 were obtained under
