基于新型热交联主体材料VB-CzTAZ的OLED器件的研究 pg电子娱乐游戏app 生物提供定制合成

为了得到溶液法制备的高性能的OLED器件, 基于咔唑和1,2,4-三氮唑基团及可热交联的苯乙烯基团, 设计并合成了可热交联的主体材料VB-CzTAZ。

测试结果表明, VB-CzTAZ具有很好的热稳定性(Td: 323 ℃), 把该材料溶于氯苯旋涂成膜, 该膜在手套箱中190 ℃下发生热交联。

不同溶剂的薄膜清洗实验表明, 热交联后的VB-CzTAZ具有优秀的抗溶剂性。

通过VB-CzTAZ盐盐溶液法治建设备的绿光磷光电子元元器, 初始化电压工作电流为5.1 V, 亮度调节为2 404 cd/m2, 工作电流利用率为4.3 cd/A, 证实该化学交联材质会应用于盐盐溶液法治建设备多层住宅OLED电子元元器。

Abstract：In order to realize the high efficiency OLEDs by solution process, a cross-linkable host material, VB-CzTAZ containing carbazole and 1,2,4-triazole units was designed and synthesized. It is found that VB-CzTAZ with styryl groups can be thermally cross-linked by curing at 190 ℃ without any polymerization initiator. Besides the excellent thermal stability (Td:323 ℃) and good surface morphology, the thermally cross-linked film of VB-CzTAZ also shows excellent solvent resistances as rinsing with different solvent. For the phosphorescent OLEDs (PhOLED) incorporating VB-CzTAZ as host, the turn-on voltage is 5.1 V, the maximum luminance is 2 404 cd/m2, and the maximum current efficiency is 4.3 cd/A, respectively. It indicates that the cross-linkable host material has potential to be used for the solution-processed multilayer PhOLED.
