Exploring Efficient Blue TADF Materials with Ultrafast Bipolar Charge Transport for High‐Efficiency Thick‐Layer OLEDs (Adv. Funct. Mater. 30/2024)

Thick-Layer OLEDs In article number 2401434, Zujin Zhao and co-workers report two tailored blue luminescent molecules consisting of ring-fused carbonyl-containing acceptors and spiro-acridine donors. They hold ultrafast bipolar charge transport and strong solid-state delayed fluorescence in neat films, and the state-of-the-art electroluminescence performances are achieved not only in thin-layer organic light-emitting diodes but also simplified thick-layer ones with obviously improved operational lifetimes.
