Blue emitters are necessary for achieving full-color displaying OLEDs, however, most blue emitters show low efficiency, short lifetime or serious efficiency roll-off, hindering the development of OLED techniques. In this research, a nonpolar sym. aggregation-induced emission (AIE) emitter was designed and constructed through facile steps, with the triphenylamine-end, anthracene-spacer and tetraphenylethene (TPE)-center. This emitter exhibited good thermal stability and aggregation-enhanced emission (AEE) characteristics, based on which non-doped blue OLED device was readily fabricated with the maximum external quantum efficiency (EQE) of 2.7% and also with no efficiency roll-off even at 1000 cd m-2, indicative of high efficiency and good stability as fluorescent emitter.
Organic Electronics published new progress about Aggregation-induced emission. 184239-35-8 belongs to class bromides-buliding-blocks, and the molecular formula is C26H18Br2, Electric Literature of 184239-35-8.
