In sum, we demonstrate how organo-functionalized polyoxometalates can be used as multifunctional platforms for supramolecular light-driven hydrogen evolution catalysis. Electrostatic solution-interactions between an anionic, Ptfunctionalized POM dyad with a cationic photosensitizer lead to light-driven charge-transfer and H2 evolution in solution. The reactivity of the dyads surpasses the purely intermolecular reference systems, and reactivity tuning of the dyads is possible by ligand exchange.
