Photophysical Processes in Rhenium(I) Diiminetricarbonyl Arylisocyanides Featuring Three Interacting Triplet Excited States
Inorganic Chemistry, 58(13), 8750–8762.
TL;DR:
The combined experimental evidence, along with the aid of electronic structure calculations, illustrates that the CNAr ligand is actively engaged in manipulating the excited-state decay in three of these molecules, wherein the triplet metal-to-ligand charge-transfer (3MLCT) state along with two distinct triplet ligand-centered (3LC) excited- state configurations (phen and CNAr) conspire to produce the resultant photophysical properties.
