Abstract
A novel organic compound containing an hole-transporting arylamine group and an electron-transporting 1,3,4-oxadiazole unit, 2-(5-(4-(diphenylamino)phenyl)-1,3,4-oxadiazol-2-yl) phenol(HPOT), was designed and synthesized by using facile multi-steps reactions with a high yield. With this synthesized compound as the ligand, a new aluminum (III) complex, tri(2-(5-(4-(diphenylamino)phenyl)-1,3,4-oxadiazol-2-yl)phenonate) aluminum, (AlPOT), was synthesized. Photoluminescence measurements showed that these two compounds emit intensely blue light under near-ultraviolet excitation with high fluorescence quantum yields of 0.76 and 0.68, respectively, while TG analysis confirmed their high heat-stability, indicating that they are high efficient blue-light-emitting materials. All the results provide a basic knowledge for the fabrication of corresponding organic light-emitting diodes.
