a series of chromophore–quencher complexes are reported. They are all comprised of a luminescent rhenium(I) tricarbonyl diimine complex that is covalently attached to anthracene or phenanthrene moieties via rigid rod-like p-xylene bridges of variable lengths. Rhenium-to-anthracene energy transfer is strongly exergonic (−ΔG0≈ 0.9 eV) and causes very efficient rhenium MLCT luminescence quenching. By contrast
