Long-lived, near-IR emission from Cr(III) under ambient conditions.

Bis-terdentate (N^N^N) ligands coordinated to Cr(III) yield complexes that display near-IR emission under aerated solvent conditions at room temperature.

Polysubstituted Ligand Framework for Color Tuning Phosphorescent Iridium(III) Complexes.

A series of ligands have been synthesized based upon a polysubstituted 2-phenylquinoxaline core structure. These ligands introduce different combinations of fluorine and methyl substituents on both the phenyl and quinoxaline constituent rings. The resultant investigation of these species as cyclometalating agents for Ir(III) gave cationic complexes of the form [Ir(C^N)(bipy)]PF (where C^N = cyclometalating ligand; bipy = 2,2'-bipyridine).
