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。

针对VB-CzTAZ氢氧化钠饱和溶液法治社会备的绿光磷光电子电子器件, 再启动线电压为5.1 V, 对比度为2 404 cd/m2, 电压电流效应为4.3 cd/A, 表示该化学交联涂料可能主要用于氢氧化钠饱和溶液法治社会备两层OLED电子电子器件。

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.
