A series of phenanthroline derivatives containing quinoxaline moieties were synthesized, and their electron-transporting properties were investigated by using N,N′-di(1-naphthyl)-N,N′-diphenyl-(1,1′-biphenyl)-4,4′-diamine (α-NPD) and tris(8-hydroxyquinolato)aluminum (Alq3) as the hole-transporting material and the emitting layer, respectively. Higher external quantum efficiency for the phenanthroline derivative than Alq3 in the electroluminescent devices at a luminance of 100 cd/m2 was obtained.
