Abstract: 

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.
