Asymmetric catalysis is of crucial importance owing to the huge and rising demand for optically pure substances. Metal-organic frameworks (MOFs) and covalent organic frameworks (COFs), as two emerging crystalline porous materials, have presented great promising applications for heterogeneous asymmetric catalysis. The unique properties, such as, highly regular porous structures, prominent structural tunability, and well-ordered catalytic sites, render chiral MOFs (CMOFs) and chiral COFs (CCOFs) highly active and enantioselective for a large number of asymmetric catalytic organic transformations. Furthermore, they provide a useful platform for facile mechanistic understanding and catalyst design. This review provides an overview of the advancements in CMOFs and CCOFs for asymmetric catalysis. The designs, syntheses and structures of these crystalline porous materials, and their asymmetric catalytic performance are described. And the perspectives on challenges and opportunities in development of CMOFs and CCOFs are discussed. It is anticipated that this review will shed light on the heterogeneous asymmetric catalysis with CMOFs and CCOFs and motivate further research in this promising field.
由于对光学纯物质的需求巨大且不断增长，不对称催化至关重要。金属有机框架（MOF）和共价有机框架（COF）作为两种新兴的晶体多孔材料，在多相不对称催化方面展现出极具前景的应用。手性金属有机框架（CMOF）和手性共价有机框架（CCOF）具有独特的性质，如高度规整的多孔结构、显著的结构可调节性以及有序排列的催化位点，使其对大量不对称催化有机转化反应具有高活性和对映选择性。此外，它们为深入理解反应机理和催化剂设计提供了有用的平台。本综述概述了CMOF和CCOF在不对称催化方面的进展。描述了这些晶体多孔材料的设计、合成和结构，以及它们的不对称催化性能。并讨论了CMOF和CCOF发展中面临的挑战和机遇。预计本综述将为CMOF和CCOF的多相不对称催化提供启示，并推动这一充满前景的领域的进一步研究。
