摘要：

Reaction of 1,2-di(imidazolyl) benzene treated with n-BuLi proceeded to give diimidazo[1,2-a:2',1'-c] quinoxaline in the presence of iodine or Pd(PPh3)(4). Blue fluorescence was observed from 3,10-diarylated diimidazoquinoxalines with high quantum yield. They were also applied to organic light-emitting devices as emitters, in which the diphenyl derivative emits a nearly pure blue light.
