Two new cyclometalated Ir(III) diiminecomplexes were used as photosensitizers for homogeneous hydrogen evolution reaction (HER). These complexes were characterized by electrochemistry, ultraviolet–visible absorption, time-resolved and steady-state photoluminescence spectroscopy as well as by theoretical methods. The metal–ligand-to-ligand charge transfer character of their lowest excited state was
