  • The bilayer heterojunction devices were fabricated successfully by using a novel oxadiazole derivative: 2, 2-(2,5-thiophenediyl) bis (5-(4-methyl) phenyl-1,3, 4-oxadiazole) (T-OXD) as the electron-transporting layer (ETL)and a pyrazoline derivative:1-phenyl-3-(dimethylamino)styryl-5-(p-(dimethylamino) phenyl)pyrazoline (PDP) as the light-emitting layer and the hole-transporting layer. The emission at 500nm was derived from PDP layer.In comparison with the bilayer device of tris (8-hydroxyquinoline) aluminum (Alq) as the ETL, the luminous efficiency of the PDP/T-OXD heterojunction device was enhanced by 104 times.

Abstract: The bilayer heterojunction devices were fabricated successfully by using a novel oxadiazole derivative: 2, 2-(2,5-thiophenediyl) bis (5-(4-methyl) phenyl-1,3, 4-oxadiazole) (T-OXD) as the electron-transporting layer (ETL)and a pyrazoline derivative:1-phenyl-3-(dimethylamino)styryl-5-(p-(dimethylamino) phenyl)pyrazoline (PDP) as the light-emitting layer and the hole-transporting layer. The emission at 500nm was derived from PDP layer.In comparison with the bilayer device of tris (8-hydroxyquinoline) aluminum (Alq) as the ETL, the luminous efficiency of the PDP/T-OXD heterojunction device was enhanced by 104 times.
