研究目的
Investigating the enhancement of electroluminescence performance in non-doped organic light-emitting diodes (OLEDs) through the development of a pivotal thermally activated delayed fluorescence (TADF) emitter DspiroAc-TRZ.
研究成果
The study successfully demonstrates that the concurrent manipulation of intermolecular aggregation behavior and monomolecular structure in DspiroAc-TRZ leads to high electroluminescence performance in non-doped OLEDs, achieving a record EQE of 25.7% for sky-blue TADF-OLEDs.
研究不足
The study focuses on the performance of DspiroAc-TRZ in non-doped OLEDs, and while it achieves high EQE, the broader applicability and scalability of the synthesis and device fabrication processes are not discussed.
