摘要：NOVELTY - A N,N'-diaryl-aryl( b)-dibenzo(f,h) quinoxaline derivative (I) is new. USE - N,N'-diaryl-aryl( b)-dibenzo(f,h) quinoxaline derivative (I) used as hole transport material of electroluminescent (EL) device. ADVANTAGE - The compound (I) has large Stokes displacement (more than 240 nm), where partial compounds have two emission bands and maximum emission wavelength of two emission bands has a difference of more than 100 nm. It has also higher highest occupied molecular orbital (HOMO) energy level, which means it has excellent electrochemical property. DETAILED DESCRIPTION - A N,N'-diaryl-aryl( b)-dibenzo(f,h) quinoxaline derivative of formula (I) is new. R1, R2=optionally substituted 6-16C aromatic ring, where substituent is 1-6C linear or branched chain alkyl or asterisk-C(O)-O-R3 (II); A=optionally substituted bivalent phenyl, where substituent is 1-6C linear or branched chain alkyl or alkoxy; and R3=1-6C linear or branched chain alkyl. An INDEPENDENT CLAIM is included for preparing the compound (I).
