英文摘要	A novel hole injecting and transporting material, NN-di(9-ethylcarbaz-3-yl)-3-methylaniline (DECMA), was prepared by one-step reaction for use in organic electroluminescent (EL) devices. Organic EL device with configuration of ITO/DECMA (60 nm)/NPB (10 nm)/Alq(3) (60 nm)/Mg:Ag/Ag turned on at 3.7 V and displayed a brightness of 1150 cd m(-2) and a current efficiency of 5.5 cd A(-1) at the current density of 20 mA cm(-2), while a reference device with configuration of ITO/NPB (70 nm)/Alq3 (60 nm)/Mg:Ag/Ag turned on at 3.9 V and exhibited a brightness of 500 cd m(-2) and a current efficiency of 2.4 cd A(-1) at the same current density. The lower turn on voltage and higher brightness and efficiency obtained in DECMA-containing device can be ascribed to the improved hole injection at anode/organic interface due to the low ionization potential of DECMA and the better balanced hole-electron recombination in emitting layer due to the moderate hole drift mobility of DECMA.
