| dc.description.abstract | Hyperfluorescent (HF) organic light-emitting diodes (OLEDs) utilizing multi-resonance (MR) type thermally activated delayed fluorescence (TADF) emitters as terminal emitters (TEs) have attracted attention for their stable, efficient device performance. Nevertheless, research to improve device lifetime remains essential, with a focus on suppressing Dexter energy transfer (DXET). In this study, we developed a bulkier TE to increase the distance between the assistant dopant (Ad) and the TE within the HF system, thereby suppressing DXET. As a result, we successfully extended the device lifetime while maintaining the EQE. | - |
