Tuning the excited‐state lifetimes of Ru(II) polypyridyl complexes is the key to their potential applicabilities, for example, as photosensitizers. In their Communication on page 667 ff. , Leticia González et al. demonstrate, with the help of quantum chemical calculations, that the different emissive properties of two similar Ru(II) polypyridyl complexes bearing peripheral ligand substitution are governed by the radiative decay rates and not the energy gap law, oppositely to what it is generally believed. This change of paradigm might be transferable to understand the fine tuning on the emissive properties of other Ru(II) polypyridyl complexes.
