Thermally activated delayed fluorescent (TADF) emitters are one of the most promising candidates for low-cost and high efficiency organic light-emitting devices (OLEDs) to realize 100% of internal quantum efficiency. In this paper, we developed a series of TADF emitters, 2-functionalized-4,6-bisl4-(9,9-dimethyl-9,10-dihydroacridinejphenyljpyrimidine called Ac-RPM. The optimized device realized a extremely high efficiency of 62 Im W-1 a high external quantum efficiency of 25%, light-blue emissions with the Commission Internationale de l’Eclairage chromaticity coordinates of (0.19, 037) and a low turn-on voltage of <3 .0 V.
