摘　　要：三苯胺类化合物具有空穴迁移率高和发光性能优异等优点,其作为OLED空穴传输材料及发光材料被广泛应用于OLED器件。本文以三苯胺为核心分别引入苯环,联苯和芴单元,设计合成了一种高热稳定性的三苯胺类空穴传输材料N-([1,1'-联苯]-4-基)-N-(2'-(9-苯-9H-芴-9-基)-[1,1'-联苯]-3-基)-[1,1'∶4',1''-三联苯]-4-胺。结果表明:目标化合物具有高的热稳定性和较好的成膜性,其热分解温度为456.5℃,玻璃化转变温度高达236.2℃。同时,该材料具有较宽的紫外吸收光谱和较大的共轭体系,在OLED空穴传输材料中具有潜在的应用前景。Triphenylamine-based compounds possess advantages such as high hole mobility and excellent luminescent properties,making them widely used as hole transport materials and luminescent materials in OLED devices.In this paper,a triphenylamine-based hole transport material,N-([1,1'-biphenyl]-4-yl)-N-(2'-(9-phenanthren-9-yl)-[1,1'-biphenyl]-3-yl)-[1,1'∶4',1''-triphenyl]-4-amine was designed and synthesized by incorporating benzene,biphenyl and fluorene units onto the core of triphenylamine.The result indicates that the target compound exhibits thermal decomposition temperature of 456.5℃and a high glass transition temperature of 236.2℃.This high glass transition temperature indicates good thermal stability and film-forming properties.Meanwhile,the material has high thermal stability.Additionally,it possesses a wide ultraviolet absorption spectrum and a large conjugated system,making it potentially suitable for applications in hole transport materials for OLEDs.
