Abstract: The development of high-performance, solution-processed, orange-red, organic light-emitting diodes (OLEDs) based on thermally activated delayed fluorescence (TADF) emitters is a challenging endeavor. In this study, two orange-red TADF emitters, namely 2DMAC-DBP-2tBuCz and 2SPAC-DBP-2tBuCz, are developed by a novel D-A-R molecular design strategy. This design makes the molecules highly soluble and inhibited concentration quenching of excitons, rendering the emitter suitable for use in devices with high concentration to boost their performance. The solution-processed, orange-red OLEDs manufactured in this study achieved a state-of-the-art maximum external quantum efficiency (EQEmax) value of 23.7% and an extremely high maximum power efficiency (PEmax) of 48.8 lm W−1, which is nearly twice higher than the previously reported best value (27.1 lm W−1). Therefore, the collaboration of molecular engineering and sophisticated device design provided a novel method for extremely low power consumption solution-processed OLEDs.
