For the fabrication of high stable organic electroluminescent device, we have synthesized amorphous molecular materials such as 1,3,5-tris(phenylphenylamino)benzene (TDAB), p-ClTDAB, p-BrTDAB and p-MetTDAB as hole transporting materials and investigated ITO/p-XTDAB (X=Br, Cl, methoxy)/Alq₃/Al device emitted green light. It has been found that organic EL device consisting of ITO/p-BrTDAB/Alq₃/Al showed high EL intensity. Especially, the durability and EL performance of organic EL device using the amorphous hole transporting material were studied.
