In this work, we demonstrate a chiral dual-core strategy for the design of high-performance organic circularly polarized aggregation-induced emission luminogens (AIEgens), which features of connecting two thermally activated delayed fluorescence (TADF) luminophore with chiral linkage that allows efficient through-space coupling (TSC) to occur. Using this strategy, a pair of dual-core enantiomers, R/S-DNKP, were designed and synthesized by linking two benzophenone derivatives with a 1,1’-bi-2-naphthol unit. Compared to the mono-core counterpart NKP, the dual-core emitters exhibited a much higher photoluminescence quantum yields of 94%. Moreover, benefited from their chiral helical folding configurations, the R/S-DNKP enantiomers exhibited a high luminescence dissymmetry factor (|glum|) value up to 1.3×10-3 in film states. Notably, the electroluminescence devices based on the R/S-DNKP enantiomers achieved external quantum efficiency values of 21.5% and 19.7% with little roll-off. It is believed that this molecular design strategy will pave new routes for the development of high-performance chiral emitters for future organic photonic devices.
