摘要 以氢键作为链接基元,合成了吡啶羧酸类的氢键液晶,通过核磁氢谱和红外光谱对所得中间体和最终产物的结构进行了分析,并且通过偏光显微镜(POM),对所得最终产物的液晶性能进行了测定,得出该类复合物具有室温液晶性和宽的相转变温度. In this paper, series of hydrogen bond self-assemble liquid crystalline compound have been synthesized with the pyridine and carboxylic acid derivates linked by hydrogen bond. The structure and property of intermediates and final products are researched through infrared spectrum （IR）, hydrogen nuclear magnetic resonance （1 H NMR） and polarizing microscope （POM）, the result shows that the complexes show mesomorphic phases at near room-temperature and board phase transition temperature.
