    • In the realm of organic light-emitting diodes (OLEDs), a significant breakthrough has been achieved by employing a platinum complex as a sensitizer and multi-resonant thermally activated delayed fluorescence (MR-TADF) molecules as emitters. This innovation has led to the development of highly efficient, high color purity OLEDs that can be processed using solutions, thereby addressing the issue of high costs associated with the vacuum deposition process. The research has successfully demonstrated an external quantum efficiency (EQE) of 13.2% with a low efficiency roll-off, and by incorporating a bulky TADF emitter, the EQE was further improved to 13.6%. This work paves the way for high-performance, solution-processed electroluminescence.
