%X Homoleptic fac-IrIIIL3 complexes
of 5-aryl-4H-1,2,4-triazole ligands are sky blue
emitters. When unsymmetrically substituted, the triazole ligands exhibit
atropisomerism, and upon cyclometalation to Ir(III) a mixture of diastereomers
is formed. We have isolated and structurally characterized all four
possible diastereomers of the fac-IrIIIL3 complex formed upon cyclometalation of an atropisomeric
5-aryl-4H-1,2,4-triazole ligand onto Ir(III). The
phosphorescent blue emitting materials reported herein are among the
most efficient to date, with quantum efficiencies above 95%.
