Highly efficient pure blue TADFmaterials (2DPAc-MPM and 2DPAc-PPM) have been
Developed, based on a central pyrimidine acceptor (A) core with peripheral diphenylacridan donor (D) units. OLEDs employing 2DPAc-MPM and 2DPAc-PPM as blue TADF emitters have achieved extremely high maximum EQE of up to 20.8%. In
addition, a high Ƞp of 31.5 lm/W and Ƞc of 38.1 cd/A have been achieved.
