Luminescent ruthenium-polypyridine complexes & phosphorus ligands: anything but a simple story

Abstract

This tutorial review presents an exhaustive picture of the luminescence studies that have been undertaken on ruthenium(ii) complexes bearing polypyridine and phosphorus(iii) ligands. The introduction of phosphorus to the Ru coordination sphere has multiple consequences on the nature and energy of the various excited states involved, but it does not necessarily rule out room temperature emission.
