Abstract | Gold(III) complexes are attractive candidates as phosphorescent dopants in organic lightemitting devices for high luminance full-colour displays. However, no data on the stability of such devices have been reported to date. Through rational molecular design and synthesis, we have successfully generated a new class of cyclometalated gold(III) C^C^N complexes with tunable emission colours spanning from sky-blue to red. These complexes exhibit high photoluminescence quantum yields of up to 80 % in solid-state thin films, excellent solubility and high thermal stability. Solution-processable and
vacuum-deposited organic light-emitting devices based on these complexes operate with external quantum efficiencies of up to 11.9 % and 21.6 %, respectively, and operational half-lifetimes of up to 83,000 h at 100 cd m−2.
