The authors investigated the EL properties of the organic light-emitting-diode (OLED) with a distyryltriphenylamine derivative (MDTPA). Although, PL and EL of MDTPA thin film was in blue region, the EL of indium-tin-oxide (ITO)/MDTPA/aluminum quinoline (Alq3)/Al was due to the emission from Alq3, but not the emission from MDTPA. It can be explained by that the emitting region is formed in Alq3 layer since MDTPA has excellent hole transportation. The authors introduced an oxadiazole dimer as carrier blocking layer between MDTPA and Alq3 layers in order to form the emitting region in MDTPA layer. This OLED was found to have a high performance for a blue-light-emitting EL device. Its luminance was over 3000cdm<sup>-2</sup> at the current density of 100mAcm<sup>-2</sup>. The EL threshold voltage was about 5 V. Using AILi alloy as the cathode instead of Al, the OLED had higher performance.
