Delayed Fluorescence and Amplified Chirality via Modified Substitution Position for Deep-red Circularly Polarized Organic Light Emitting-diodes

Published: May 14, 2024

Developing easily accessible deep-red/near-infrared circularly polarized emitters for practical organic light-emitting diodes remains a significant challenge. Here, strategy has been proposed developing deep-red delayed fluorescent based on novel chiral acceptor platform. By changing triphenylamine (TPA) substitution position from para to meta, R/S-M-TBBTCN demonstrated thermally activated fluorescence (TADF) properties with lifetime of 6.6 μs that R/S-P-TBBTCN doesn’t have. Furthermore, showed 20 nm red-shift in emission and 10-fold enhancement asymmetry factor (glum), compared R/S-P-TBBTCN. The solution-processed nondoped (CP-OLEDs) R-M-TBBTCN display 2.2% external quantum efficiency.
