摘　　要：氢键在材料科学、化学等方面具有重要的作用。对氢键的强度和本质进行深入的研究具有重要的意义。Zheng等对苯甲酸-吡啶的超分子液晶合成进行了研究,通过改变苯甲酸的结构,对超分子液晶的结构和性质进行了研究。以吡啶作为质子受体分子,苯甲酸作为质子供体分子,不同取代基对O-H…N氢键强度的影响。Hydrogen bonding plays an important role in material science and chemistryIt is of great significance to further study the strength and nature of hydrogen bonds.Zheng et al.studied the synthesis of supramolecular liquid crystals of benzoic acid-pyridine.By changing the structure of benzoic acid,the structure and properties of supramolecular liquid crystals were studied.In this paper,pyridine was chosen as proton receptor molecule and benzoic acid as proton donor molecule.The effect of different substituents on the strength of O-H N hydrogen bond was studied.
