Abstract

合成了一种新的具有“双极”(bipolar)性质的有机小分子蓝色发光材料2-(5-(4-(二苯胺基)苯基)-1,3,4-噁二唑-2-)苯酚[2(5-(4-(diphenylamino)phenyl)-1,3,4-oxadiazol-2-yl)phenol, HPOT],并以HPOT为配体, 与铝离子配位,合成了三(2-(5-(4-(二苯胺基)苯基)1,3,4-噁二唑-2-)苯酚)合铝[tri(2-(5-(4-(diphenylamino)phenyl)-1,3,4-oxadiazol-2-yl)phenonate)aluminum, AlPOT]配合物。 用 1 H NMR、 HRMS和元素分析进行了表征,并测定了两种化合物的光致发光性质和热稳定性。 结果表明:两种新化合物的热稳定性好,光致发光性能优良,是制作有机电致发光器件的候选材料。

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.
