摘要
合成了侧链含苯甲酸的苯乙烯／马来酸单酯共聚物（ＭＥ－ＳＭＡ）和４－苯乙烯基吡啶（４ＳＺ）。以ＴＨＦ为溶剂，制备了以ＭＥ－ＳＭＡ为质子给体，４ＳＺ为质子受体的氢键复合物。用ＤＳＣ和偏光显微镜（ＰＯＭ）研究两者复合前后的液晶行为。结果表明形成的氢键复合物在２０３℃～３３４℃呈现向列相液晶态，并用ＩＲ证实了分子间氢键的存在。
Monoester of P(styrene-co-maleic anhydride) (ME-SMA) containing a 4-oxybenzoic acid unit in its side-chain and 4-stilbazole (4SZ) were synthesized in this paper. The complex was prepared by slowing evaportion from THF solution containing equimolar of ME-SMA and 4SZ with vacuum drying at 50℃ for 24h. DTA and polarized optical microscope (POM) were utilized to investigate the liquid crystal behavior of complex. IR spectra of the complex shows the existence of the intermolecular hydrogen bonds between carboxyl group and pyridine ring. The generation of liquid crystalline phase induced by hydrogen bonds from copolymer is unprecedented. Furthermore, this approach offers a relatively simple route for the liquid crystallization of universal polymers, such as SMA.
