摘要/Abstract

超分子手性组装体通常由多种非共价相互作用协同驱动形成, 是一类具有独特手性限域微环境的软物质, 对材料工程、生命科学、光学器件、催化合成等领域的发展具有重要作用. 其主要构建方法分为三种: 手性基元组装、手性因素诱导非手性基元组装、非手性基元对称性破缺组装. 通过分析近年来的研究成果, 归纳了利用这三种方法构建超分子手性组装体的一般策略, 并简要综述了超分子手性组装体在手性模板、手性识别、圆偏振发光及不对称催化领域中的应用进展与亟需弥补的缺陷. 随着研究的深入, 手性传递机制将得到进一步解释, 未来将有助于人们理解生命体内的手性现象, 有望最终解答自然界中的手性起源问题.

As a kind of soft materials promoted by multiple noncovalent interactions, supramolecular chiral assemblies own the distinctive confined chiral microenvironment and play an important role in material engineering, life science, optical devices and catalytic synthesis. In general, supramolecular chiral assembles can be fabricated through the assembly of chiral molecules, or a combination of achiral molecules and chiral inducements, or mere achiral molecules in symmetry breaking manner. In this paper, the general fabrication strategies of supramolecular chiral assemblies in recent years are summarized, and their improvements in chiral template, chiral recognition, circularly polarized luminescence and asymmetric catalysis are briefly reviewed, as well as the shortcomings in these fields. With the development of supramolecular chiral assemblies, the mechanism of chirality transfer will be explained in depth in future, which may help us understand the chirality phenomenon in organism and give a clue to answer to the origin of homochirality in nature.
Key words: supramolecular chiral assembly, chiral template, chiral recognition, circularly polarized luminescence, asymmetric catalysis
