In this work, six perylene bisimide-based red emitters, N,N''-bis(2-decyltetradecyl)-1-([1,1':3',1''-terphenyl]-5'-yl)perylene-3,4,9,10-diimide(STPH),N,N'-bis(2-decyltetradecyl)-1,7-bis([1,1':3',1''-terphenyl]-5'-yl)perylene-3,4,9,10-diimide(DTPH), N,N''-bis(2-decyltetradecyl)-1-(5'-phenyl-[1,1':3',1''-terphenyl]-4-yl)perylene-3,4,9,10-diimide(STRPH), N,N0-bis(2-decyltetradecyl)-1,7-bis(5'-phenyl-[1,1':3',1''-terphenyl]-4-yl)perylene-3,4,9,10-diimide(DTRPH),N,N0-bis(2-decyltetradecyl)-1-(4-(2,2-diphenylvinyl)phenyl)perylene-3,4,9,10-diimide(STTPE) and N,N'-bis(2-decyltetradecyl)-1,7-bis(4-(2,2-diphenylvinyl)phenyl)perylene-3,4,9,10-diimide(DTTPE), with the excellent chemical, thermal and photo-chemical stability, are synthesized through the convenient Suzuki coupling reaction, in which, the fluorescent properties can be modified easily from ACQ to AIE by just simply changing the bulky volume of the introduced aromatic substituents. After being fabricated into organic light-emitting diodes, STRPH exhibits the best performance with the maximum luminescence, power efficiency, current efficiency and external quantum efficiency of 1,948 cd m^(-2), 2.04 lm W^(-1), 5.85 cd A^(-1), 4.93% at Commission Internationale de L'Eclairage(CIE) coordinates of(0.56, 0.34),as the result of the high efficient energy transfer and good energy match achieved in the device. 关键词：衍生物淡色啤酒设备性质 ACQ 可调节排放马厩
