제목 A study on the effects of secondary acceptor on the emission properties of thermally activated delayed fluorescence emitters.
초록 TADF emitters adopting a pyridine secondary acceptor derived molecular design were developed in order to shorten the delayed fluorescence lifetime and enhance the efficiency roll-off while achieving high EQE. The TADF emitter with a methyl substituted pyridine secondary acceptor achieved high external quantum efficiency over 20% and little efficiency roll-off up to 1,000cd/m2. Therefore, the pyridine secondary acceptor based molecular design was effective to manage the delayed fluorescence lifetime of the TADF emitters and efficiency roll-off of the TADF devices.
