The triplet excitons in35Cbz4BzCNcan be effectively harvested by phosphorescence and thermally activated delayed fluorescence emitters. In the 4CzIPN doped device, the best performance of a maximum current efficiency of 111.8 cd A?1, power efficiency of 86.8 lm W?1, and external quantum efficiency of 31.7% with a small efficiency roll-off of 103 cd A?1at 1000 cd m?2has been achieved.35Cbz4BzCNis also compatible with FIrpic to give sky-blue emission up to 46.3 cd A?1and with TXO-TPA to give orange-red emission up to 60.6 cd A?1efficiency. ?
