A dyad complex has been constructed as a soluble molecular model of a heterogeneous cobalt‐based oxygen‐evolving catalyst (Co‐OEC). To this end, the Co 4 O 4 core of a cobalt‐oxo cubane was covalently appended to Re I photosensitisers. The resulting adduct was characterised both in the solid state (by X‐ray diffraction) and in solution using a variety of techniques. In particular, the covalent attachment of the Re I moieties to the Co 4 O 4 core promotes emission quenching of the Re I photocentres, with implications for the energy and electron transduction process of Co‐OEC‐like catalysts.
