Abstract A molecular donor–acceptor dyad comprising a hexarhenium cluster core, [Re 6 (μ 3 ‐ Se) 8 ] 2+ , and a fullerene moiety which are covalently linked through a pyridine ligand was synthesized and fully characterized. The electrochemical and photophysical properties are reported. The detailed study includes cyclic voltammetry, steady ‐ state absorption and fluorescence spectroscopy, radiation chemistry and transient absorption spectroscopy. A light ‐ induced electron transfer between the inorganic cluster moiety and the fullerene can be excluded. However, a light ‐ induced energy transfer from the rhenium cluster to the fullerene is proposed.
