Abstract

Different from the previous design strategy, herein, a cationic Ir(III) complex ([(ptbi)₂Ir(bisq)]Cl) with a small chlorine as the counterion was synthesized, which realized the formation of a solid film via a vacuum-deposition process. The white OLED, employing it as an orange-emitting layer, achieved excellent performances with a brightness of 50 122 cd m⁻², a CE of 25.5 cd A⁻¹, an EQE of 13.1%, accompanied by a low CE efficiency roll-off of 4.7%. These are the best results among evaporated cationic Ir(III)-based white OLEDs reported so far.
