摘　　要：采用缩聚反应合成了两种未见报道的含三芳胺聚西夫碱空穴输送材料 (PC - 1,PC - 2 ) ,该材料具有非晶态结构、良好的热稳定性和空穴传输性 .用IR ,UV -Vis,1HNMR对所合成的聚合物进行了表征 ;用XRD技术对在不同溶剂中得到的聚合物的结晶现象进行了研究 ;用热重分析 (TG)和差热分析 (DTA)技术对材料在氮气中的热稳定性进行了研究 ,并进一步用量子化学从头算方法 ,对电离热 (Ip)和前线轨道能进行了计算 .结果表明 ,用二甲苯为溶剂得到的聚合物无结晶现象 ,PC - 1,PC -Two polyschiff's base containing triarylated amine hol-transporting materials (PC-1, PC-2) that were never reported were synthesized by polycondensation. The materials with noncrystallization structure have fine thermal stability and cavity transportation properties. The structures of the condensed polymers were characterized by Infrared, UV-Vis and 1H NMR spectra. The crystalline actions of the condensed polymers that were synthesized from different solvents were investigated by X-ray diffraction technology. The result indicated that no crystalline phenomenon occurred when the solvent was dimethyl benzene. Through thermal gravity (TG) and differential thermal analysis (DTA), the thermal stability of the condensed polymers was performed in the presence of N 2. The ionization energy and advanced linear orbital level were calculated by quantum chemical initial calculation method. The results indicated that PC-1 and PC-2 have fine thermal stability and cavity transportation properties.
