Abstract: An artificial [FeFe]-hydrogenase ([FeFe]-H2ase) mimic 3II, consisting of dual organic chromophores covalently assembled to the [Fe2S2] active site, was constructed for light-driven hydrogen evolution. The structural conformation of synthetic photocatalyst was characterized crystallographically and spectroscopically. The photo-induced intramolecular electron transfer was evidently demonstrated by the combination of electrochemical, steady-state, and transient absorption spectroscopic studies. Finally, a remarkable activity was obtained in the present photocatalytic system, indicating the covalent incorporation of photosensitizer and catalytic center as a promising strategy to construct inexpensive, easily accessible [FeFe]-H2ase model photocatalysts.
