为了提高有机电致发光器件的热稳定性，合成了新型空穴和电子输运材料。分别基于三苯胺（TPA）和恶二唑（OXD）基团设计了这种空穴和电子传递材料的分子结构。结果表明，所制备的材料具有超过100°C的高玻璃化转变温度（Tg），真空沉积薄膜具有明显的热稳定性。对于采用新型空穴传输材料和典型发射材料三（8-喹啉）铝的双层EL器件，热稳定性明显依赖于空穴传输材料的Tg；获得了优异的热稳定性。采用新型输运材料制备的三层电致发光器件具有良好的发射效率和稳定性。电子传递材料也被应用于以聚乙烯咔唑为基体的聚合物体系中。
Novel hole and electron transporting materials have been synthesized to improve the thermal stability of organic electroluminescent (EL) devices. Molecular structures of such hole and electron transporting materials were designed based on triphenylamine (TPA) and oxadiazole (OXD) moieties, respectively. It has been found that the resulting materials have high glass transition temperatures (Tg) over 100°C and the vacuum-deposited thin films are significantly thermally stable. For the two-layer EL devices using the novel hole transporting materials and the typical emitting material, tris(8-quinolinolato) aluminum, the thermal stability has been clearly seen to depend on the Tg of the hole transporting material; excellent thermal stability was achieved. For the three-layer EL device using the novel electron transporting material, good emission efficiency and good stability were achieved. The electron transporting materials have been also applied to the polymeric system with polyvinylcarbazole matrix.
