Toss the F : A new series of Ir III 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 C 2 )(bptz)(PMe 2 Ph)] (see structure; bptz=3‐ tert ‐butyl‐5‐(2‐pyridyl)‐1,2,4‐triazolate; P C 2 =dicyclometalated phosphite tripod) show outstanding performance.
