Iridium(III) Complexes of a Dicyclometalated Phosphite Tripod Ligand: Strategy to Achieve Blue Phosphorescence Without Fluorine Substituents and Fabrication of OLEDs

Abstract

Toss the F: A new series of IrIII complexes functionalized with pyridyltriazolate chromophores and a tripodal dicyclometalated phosphite achieved highly efficient blue phosphorescence without employing any fluorine substituents. OLEDs with dopant [Ir(P C2)(bptz)(PMe2Ph)] (see structure; bptz=3-tert-butyl-5-(2-pyridyl)-1,2,4-triazolate; P C2=dicyclometalated phosphite tripod) show outstanding performance.
