摘要
Solution-processed organic light emitting diodes (OLEDs) have been fabricated using the thermally activated delayed fluorescence (TADF) emitter, DACT-II, and its soluble derivative, tBu-DACT-II, as emitting dopants. DACT-II reportedly exhibits very high external quantum efficiencies (EQEs) in vacuum-processed OLEDs. The solution-processed DACT-II-based and tBu-DACT-II-based OLEDs exhibited external quantum efficiency exceeding the theoretical upper limit of classical fluorescent OLEDs.
