Effective Energy Transfer

High-efficiency blue organic light-emitting devices (OLEDs) have been fabricated using tetraphenylethene (TPE)-based conjugated molecule TPE-2Cz, which exhibited aggregation induced emission (AIE) properties, as blue host material and BUBD-1 as dopant emitter. With an optimized device structure, the effective energy transfer from the AIE host to BUBD-1 was achieved. The optimized device exhibits the peak EL efficiencies of 10.3 cd/A, 5.4% and 9.8 lm/W, with Commission Internationale de l'Eclairage coordinates of (0.15, 0.31) and a maximum luminance of 14550 cd/m2.
