主 题：Amplified chirality Deep-red circularly polarized organic light emitting-diode Binaphthol based chiral acceptor
摘 要：Developing easily accessible deep-red/near-infrared circularly polarized emitters for practical organic light-emitting diodes remains a significant ***,a practical strategy has been proposed for developing deep-red circularly polarized delayed fluorescent emitters based on a novel chiral acceptor *** changing triphenylamine(TPA)substitution position from para to meta,R/S-M-TBBTCN demonstrated thermally activated delayed fluorescence(TADF)properties with a delayed lifetime of 6.6µs that R/S-P-TBBTCN doesn’t ***,R/S-M-TBBTCN showed a 65 nm red-shift in emission and a 10-fold enhancement in asymmetry factor(glum),compared with R/*** solution-processed nondoped circularly polarized organic light-emitting diodes(CP-OLEDs)based on R-M-TBBTCN display deep-red emission and 2.2%external quantum efficiency.
