Özet

We report the step-by-step synthesis of a precious metal-free acceptor-chromophore-relay-catalyst tetrad assembly that exhibits a turnover frequency (TOF) of 7.5 x 10-3 s-1 under neutral conditions. Transient absorption spectroscopic studies indicate that upon fullerenol incorporation into the investigated complexes, charge separation efficiency increases considerably. A covalently linked tetrad assembly, with an acceptor fullerenol group, an organic chromophore, a relay Fe site, and a catalytic Co site, is designed to facilitate the charge transfer and separation process for light-driven water oxidation.
