The energy gap law for NIR-phosphorescent Cr(iii) complexes

A series of homoleptic Cr(iii) complexes containing substituted anionic 1,3-bis(pyridin-2-ylimino)isoindolin-2-ide ligands are phosphorescent with lambda(max) in the 777-970 nm range in degassed fluid solutions. The energy gap law has been successfully applied to the doublet excited states of Cr(iii) complexes.
