摘要：

设计合成了3-[2-(8-羟基喹啉基)-乙烯基]-N-对甲苯基咔唑(8)和3-[2-(8-羟基喹啉基)-乙烯基]-N-对甲氧苯基咔唑(9)及其金属锌配合物(10和11), 用UV-Vis, FTIR, ESI-MS, FAB-MS, 1H NMR和元素分析确认了化合物的结构. 热重分析实验结果表明, 金属锌配合物(10和11)有很好的热稳定性, 这对真空蒸镀制电致发光器件是有益的. 金属锌配合物组装成有机单层发光器件的结构为ITO/Organ layer(50 nm)/Al(100 nm), 其荧光发射峰分别位于592和583 nm, 为稳定的黄色光. 这两个发光器件的最大亮度分别为489和402 cd/m2, 最大电流效率分别为0.41和1.81 cd/A. 电致发光研究表明, 通过化学修饰8-羟基喹啉的2-位取代基可以改变这两个金属锌配合物的电致发光性能.

Abstract:

The (E)-2-[2-(9-p-tolyl-9H-carbazol-3-yl)vinyl]-8-hydroxyquinoline(8), (E)-2-{2-[9-(4-methoxyphenyl)-9H-carbazol-3-yl]vinyl}-8-hydroxyquinoline(9) and their zinc(Ⅱ) complexes (10 and 11) were synthesized and confirmed by UV-Vis, FTIR, ESI-MS, FAB-MS, 1H NMR and elemental analysis. The thermal analysis results indicate that complexes 10 and 11 have good thermal stability, which is very essential for fabricating stable organic electroluminescent devices. The single-layer OLEDs with structure of ITO/Organ layer(50 nm)/Al(100 nm) were prepared based on them all emit yellow, in which the peak emission of electroluminescent were 592, 583 nm individually. The OLED based on complex 10 exhibited better device performance with a maximum luminance of 489 cd/m2 and luminance efficiency of 0.41 cd/A than those of the device fabricated by complex 11, which were 402 cd/m2, and 1.81 cd/A. The electroluminescent studies carried out on the two newly synthesized Zn(Ⅱ) complexes clearly demonstrate that fine control of the electroluminescent properties is possible through the modification of substitute in position 2 of the 8-hydroxyquinoline rings.
