Abstract

In this work, an orange fluorescent material (TA-DF-BDM) with aggregation-induced emission (AIE) and mechanochromic luminescence (MCL) properties were synthesized and characterized. TA-DF-BDM had shown a clearer MCL with a larger emission color change from 507 to 625 nm upon mechanical grinding. Moreover, when TA-DF-BDM as the emitter was applied in OLEDs, the resulting doped device exhibited excellent electroluminescent properties with the maximum luminance, CE, PE, and EQE reaching 11040 cd/m2, 11.76 cd/A, 9.08 lm/W, and 3.89%, respectively.
