Dinuclear cyclometalated iridium (III) complex containing functionalized triphenylamine core: synthesis, photophysics and application in the single-emissive-layer WOLEDs

A novel triphenylamine-functionalized dinuclear iridium (III) complex of C8TPA(FIrpic)2 was synthesized and characterized. White emission with a rising brightness of 1770 cd/m2 and current efficiency of 1.31 cd/A was obtained in the single-emissive-layer OLEDs with a configuration of ITO/PEDOT:PSS/C8TPA(FIrpic)2 (10 wt %):TCTA/TPBi/LiF/Al using C8TPA(FIrpic)2 as a single-component emitter.
