Description	Journal: Angewandte Chemie International Edition A photocatalytic system containing a perylene bisimide (PBI) dye as photosensitizer anchored to titanium dioxide (TiO 2 ) nanoparticles through carboxyl groups was constructed. Under solar light irradiation in the presence of sacrificial triethanolamine (TEOA) in neutral and basic conditions (pH = 8.5), a reaction cascade is initiated where the PBI molecule firstly absorbs green light, followed by the formation of a stable radical anion (PBI •‐ ), which in a second step absorbs near‐infrared light, followed by the formation of a stable PBI dianion (PBI 2‐ ). At last, the dianion absorbs red light and subsequently injects an electron into the TiO 2 nanoparticle that is coated with platinum co‐catalyst for hydrogen evolution. The hydrogen evolution rates (HERs) are as high as 1216 and 1022 μmol·h ‐1 ·g ‐1 with simulated sunlight irradiation in neutral and basic conditions, respectively. The consecutive charging process of TiO 2 ‐surface bound electron‐poor PBI into electron‐rich PBI dianion offers an efficient strategy for photocatalytic hydrogen generation in aqueous phase.
