摘要
近年来,宏观超分子组装已经逐渐发展成为超分子化学中的一个新兴研究方向.宏观超分子组装是指特征尺寸在微米及微米以上尺度的构筑基元,通过分子间相互作用发生组装,形成有序结构的过程,是实现"全尺度自组装"不可或缺的环节,为超分子体相材料的制备提供了新的理念和方案.本文从宏观超分子组装的发展概况、设计原则与策略和应用方向3个方面展开综述,介绍了从基于长程作用力的"宏观组装"到基于分子间相互作用的"宏观超分子组装"的区别与联系,阐释了实现宏观超分子组装的设计原则和相关机理.最后,针对实现超分子材料广泛应用的目标,从"精准组装"的角度综述了提高组装结构有序程度的方法,以及宏观超分子组装在组织工程支架等方面的应用前景.
Recently macroscopic supramolecular assembly has been developed as a new research branch of supramolecular chemistry. It is defined as the process to assemble the building blocks with a feature size of micrometer or beyond micrometer through intermolecular interactions, leading to ordered structures. This research has been an important part for the realization of the ＂Self-assembly at All Scales＂ concept and provided new ideas and solutions to the fabrication of supramolecular bulk materials. This review will cover the general development, designing principle and strategies and application possibilities of macroscopic supramolecular assembly. We have clarified both the difference and correlation between macroscopic assembly based on long-range forces and macroscopic supramolecular assembly through intermolecular interactions, and interpreted the principle and mechanism to realize macroscopic supramolecular assembly. Finally, for the goal of promoting wide applications of supramolecular materials, we summarized methods to improve the ordering degree of the assembled structures with the concept of ＂precise assembly＂ and the promising possible uses in the fields of tissue engineering scaffold etc.
