摘　　要：以异烟酸、对硝基苯酚为主要原料首先合成了一种介晶基元异烟酸对硝基苯酚酯,然后以聚乙烯醇(PVA)分子的羟基氢为电子受体,异烟酸对硝基苯酚酯分子中的氮原子为电子供体,通过氢键自组装制备了氢键组装PVA侧链液晶高分子.用IR和1HNMR对介晶基元异烟酸对硝基苯酚酯和氢键组装PVA侧链液晶高分子的结构进行了表征,用DSC和热台偏光显微镜(POM)对它们的液晶行为进行了分析.结果表明,所合成的异烟酸对硝基苯酚酯和氢键组装PVA侧链液晶高分子均显示出热致液晶性能.The Liquid chain liquid crystalline Crystal compound p-nitrophenol isonicotinate was synthesized first, then PVA side- polymer was prepared by a self-assembly process using poly （ vinyl alcohol） as hydrogen bond donor and p-nitrophenol isonicotinate as the acceptor. The chemical structure of the Liquid Crystal compound and the side-chain liquid crystalline polymer was confirmed by IR and ^1 HNMR, The liquid crystalline properties of the Liquid Crystal compound and the side - chain liquid crystalline polymer was investigated by DSC and POM with hot stage. The results showed that they exhibited themotropic liquid crystal behavior.
