摘　　要：介绍了近十几年来典型的氢键组装的超分子液晶材料的组装方法和分子结构,对比其光电性能和自组装特点,并对其在光电器件方面的应用进行展望。这类材料依据氢键组装的方式和分子结构主要分为两大类:结构封闭型和结构开放型。与后者相比,前者具有易于结构修饰和易于精确调控性能的特点。但两者内部的分子结构变化时,组装的超分子液晶材料的性能均受到显著影响。分子间氢键作用组装的超分子液晶材料具有高度有序性和可精确调控性,因此作为新型材料在有机光电器件和纳米器件等领域具有广阔的应用前景。In this paper,the typical hydrogen bond-assembled supramolecular liquid crystal materials are summarized over the past decade.Their preparation methods and molecular structures are presented,and their photoelectric properties and self-assembly characteristics are compared,as well as their applications in optoelectronic devices are prospected.According to the kinds of hydrogen bonds and the molecular structures,these materials are mainly divided into two categories:closed-type and open-type structures.Compared with the latter,the former has the characteristics of easy structural modification and precise structure control.However,the properties of all these assembled supramolecular liquid crystal materials are significantly affected by the changes of their internal molecular structure.These materials assembled by intermolecular hydrogen bonding are highly ordered and their molecular structures are precisely controllable.As a novel material,it has broad application prospects in the field of organic photoelectronic devices and nanodevices.
