Waterproof complexes : Cationic Ir III photosensitizers (PSs) with an ancillary 4,4′‐bis(4‐(triphenylsilyl)phenyl)‐2,2′‐bipyridine ligand enabled hydrogen evolution from water with high turnover numbers (TONs; see scheme). The peripheral triphenylsilyl moieties prevent ligand substitution by solvent molecules, such as water, and thus increase the durability of the complexes. SR=sacrificial reducing agent, WRC=water‐reduction catalyst.
