摘要/Abstract

手性金属-有机框架具有框架结构多样性和功能可调性等特点，在对映异构体的识别与分离和不对称催化等领域中具有重要的应用.近年来，关于手性金属-有机框架的应用还扩展到其它研究领域，如在圆偏振荧光和手性铁电体等方面的研究中.与非手性金属-有机框架相比，手性金属-有机框架的设计不但要考虑手性的引入途径，还要考虑其结晶与纯化，因此在合成上相对困难.本综述论述了三种构筑手性金属-有机框架的有效策略，包括直接利用手性配体合成、非手性配体的自发拆分或手性模板诱导合成和非手性金属-有机框架的手性化.对近年来手性金属-有机框架在手性分子识别、对映异构体分离、不对称催化、圆偏振荧光以及手性铁电体等方面的研究进展进行了讨论.

Chiral metal-organic frameworks have shown important applications in the identification and separation of enantiomers and asymmetric heterogeneous catalysis, owing to their structural diversities and multifunctionalities. Recently, the applications of chiral metal-organic frameworks have been expanded to other research fields, such as circularly polarized luminescence and chiral ferroelectrics. Compared with achiral metal-organic frameworks, it is highly challenging to synthesize chiral metal-organic frameworks, because the chirality introduction usually results in the difficulty of the crystallization and purification process for the design of chiral metal-organic frameworks. In this review, we discussed three main strategies that have been utilized to construct chiral metal-organic frameworks, including direct synthesis by chiral ligands, spontaneous resolution with achiral ligands or in the presence of chiral-template, and post-synthetic modification of achiral metal-organic frameworks. Moreover, the recent research progresses of chiral metal-organic frameworks in chiral molecular recognition, enantiomer separation, asymmetric catalysis, circularly polarized luminescence, and chiral ferroelectrics are discussed.
