Abstract
We report boron based deep blue thermally activated delayed fluorescence (TADF) materials and its hyperfluorescence (HF) devices. Our synthesized new two TADF materials exhibited high external quantum efficiency (EQE)s>32%. Especially, its HF device shows the high EQE of 39.9% and 19 nm of narrow full width at half medium. We analyzed that such high device efficiency is mainly attributed to the high orientation factor, enhanced photoluminescence quantum yield, and TADF characteristic of final dopant with high Förster resonance energy transfer.
