Abstract Three series of monomers, polymers and thioester cyclic compounds containing 4H-1,2,4-triazol-3-thiol moiety were synthesized and examined for their liquidcrystalline properties. All monomers, polymers and thioester compounds were characterized by elemental analysis and FTIR, 1H-NMR and mass spectroscopy. The phase transition and mesomorphic properties were investigated by polarized optical
摘要 合成了含4H-1,2,4-三唑-3-硫醇部分的三个系列单体、聚合物和硫酯环状化合物,并考察了它们的液晶性质。所有单体、聚合物和硫酯化合物均通过元素分析和 FTIR、1H-NMR 和质谱进行表征。通过偏光显微镜(POM)和差示扫描量热法(DSC)研究相变和介晶性质。具有末端苯基取代基的单体显示出向列和近晶 A (SmA) 中间相的二态性。衍生自丙烯酸和苯基丙烯酸单体的相应聚合物显示出向列中间相。衍生自对苯二甲酰氯的唯一硫酯环状化合物显示向列中间相。
