摘要

A chiral metal-organic framework (CMOF) with accessible binding pockets and multiple recognition sites is constructed from a tricarboxylate ligand derived from phenylalanine. The CMOF features a rare structure with cavities encapsulated by a non-coordinated amino-acid moiety. It has been proven to be an efficient and recyclable chiral host, enabling adsorbing and separating racemic alcohols, diols, and epoxides with excellent enantioselectivity.
