Abstract

Gold(III) complexes supported by C-deprotonated fluorene-C^N^C ligands having high emission quantum yield up to 0.61 and long-lived emissive excited states are used as yellow emitters in color tunable PLEDs and OLEDs. High EQEs of 13.16% and 22.02% are achieved in the best PLED and OLED, respectively.

Keywords: color tunable; gold(III) complexes; high efficiency; long-lived excited state; polymer light-emitting devices.
