中文摘要：

基于C=O…HN的分子间氢键能够自组装形成具有精确分子排列和很好稳定性的有序结构,在设计构造液晶功能材料方面具有重要的不可替代的地位.分子形状是设计小分子热致液晶的一个主要考虑因素,它对液晶态的结构有至关重要的影响.以分子形状与液晶态相互关系为主线,重点介绍了目前文献报道的基于C=O…HN分子间氢键的盘状和楔形分子形成液晶的研究进展,以期为新型液晶材料的分子设计提供一些借鉴.

英文摘要：

The C=O…HN intermolecular hydrogen bonding is very important in building highly func-tional soft materials because it can form ordered structures of defined geometry and stability through self-assembly.Molecular shape is an important factor in design low-weight molecular thermotropic liquid crystals,and it has a strong impact on mesophases.This paper presents a brief review on the molecular shape-property relationships and the recent progress in supramolecules liquid crystals of discotic and tapered molecules based on C=O…HN intermolecular hydrogen bonding,which might be the guidance for design-ing novel liquid crystals.
