Abstract Photosensitizer‐assisted photocatalytic systems offer a solution to overcome the limitations of inherent light harvesting capabilities in catalysts. However, achieving efficient charge transfer between dissociative photosensitizer and catalyst poses significant challenge. Incorporating photosensitive components into reactive centers establish well‐defined channels is expected effectively address this issue. Herein, electrostatic‐driven self‐assembly method utilized integrate photosensitizers metal–organic frameworks, constructing atomically Ru‐Cu bi‐functional units promote local electron migration. Within newly constructed system, [Ru(bpy) 2 ] 2+ component Cu site serve as catalytic active for photocarrier generation H O production, respectively, their integration significantly reduces barriers transfer. Ultrafast spectroscopy situ characterization unveil accelerated directional over units, presenting orders magnitude improvement systems. As result, 37.2‐fold enhancement rate (570.9 µmol g −1 h ) that system (15.3 achieved. This work presents promising strategy integrating atomic‐scale achieve ultrafast enhanced performance.
