摘要：
Three triarylboron-based TADF emitters are developed by integrating electron-donating phenoxazine units and electron-accepting triaryl-boron units. Employing these TADF emitters in the solution-processed organic light-emitting diodes achieves a maximum external quantum efficiency of 13.9% and slight efficiency roll-off.
