摘要
近年来,由于氢键作用对聚合物的热力学性质、微观自组装、结晶及液晶行为的重要影响,氢键识别在超分子聚合物的分子设计与结构控制方面的应用受到广泛关注。本文系统介绍了氢键识别体系的类型与性质,以及分子结构、分子内氢键对氢键识别强度的影响,讨论了羧酸与吡啶间氢键识别体系、与核苷相关的氢键识别体系以及四重氢键识别体系在超分子聚合物中的最新应用,主要介绍了氢键识别超分子聚合物的合成、结构、性质及功能。
The application of hydrogen bonding recognition in designing and controlling over supramolecular polymers has attracted great attention recently due to the influence of hydrogen bonds on the thermodynamic properties, microscopic self-assembling, crystallizing and liquid crystallizing behaviors of such polymers. In this paper, the types and characters of hydrogen bonding systems, and the influences of molecular structures and intermolecular hydrogen bonds on the stability of hydrogen bonding systems are described systematically. The recent applications of hydrogen bonding recognition systems, including carboxylic acids and pyridine based system, nucleobase derived system and quadrupolar hydrogen bonding system, in supramolecular polymers are introduced. The synthetic methods, structures, properties and functions of hydrogen bonded supramolecular polymers are mainly addressed.
