Abstract

original image

Stay tuned: Tuning the excited state lifetimes of RuII polypyridyl complexes is the key to their potential applicabilities, for example, as photosensitizers. This work demonstrates that the different emissive properties of two similar RuII polypyridyl complexes bearing peripheral ligand substitution are governed by the radiative decay rates and not the energy gap law.
