Chiral zeolitic materials: Structural insights and synthetic challenges

Chiral zeolitic materials are of both fundamental and practical interest because they can combine both shape selectivity and enantioselectivity, which are desirable for asymmetric catalysis and separation. However, the synthesis of such materials remains a significant challenge in the field of zeolite science. This feature article will focus on a family of four-connected zeolite frameworks and related inorganic open frameworks with fascinating chiral structural features, aiming to provide an insight into the origin of chirality in these structures. Some approaches to the design of chiral zeolite frameworks, as well as synthesis routes and challenges to the chiral zeolitic materials are also discussed.
