Integration of fine-tuned chiral donor with hybrid long/short-range charge-transfer for high-performance circularly polarized electroluminescence

The synergistic integration of a fine-tuned chiral donor with a hybrid long/short-range charge-transfer mechanism offers an accessible pathway to construct highly efficient circularly polarized emitters. Consequently, a notable dissymmetry factor of 1.6 × 10 −3 , concomitantly with a record-setting maximum external quantum efficiency of 37.4%, is synchronously realized within a single embodiment. Synergistic integration of a fine-tuned chiral donor with hybrid long/short-range charge-transfer offers desirable circularly polarized emitters with both a high dissymmetry factor of 1.6 × 10 −3 and maximum external quantum efficiency of 37.4%.
