Metal‐Organic Frameworks as a New Platform for Enantioselective Separations

Abstract

AbstractThe enantioselective separation of racemic mixtures is highly important in the pharmaceutical, food and agrochemical sector. Metal‐organic frameworks, as a class of highly porous materials are emerging as highly efficient and selective platforms for chiral recognition and separation owing to their ultrahigh porosities, functionalized pore walls, controllable pore chemistry and presence of highly ordered chiral recognition sites. In this review, we summarize the progress made in the synthesis of chiral MOFs via direct and indirect methods, followed by their applications in some important chiral separations of alcohols, drugs, amino acids, biologically relevant molecules and important chiral organic mixtures. The developments in chiral MOF membranes as thin films for practical industrial use are also explored. Finally, the outlook for the MOFs as emerging platforms for enantioseparation and the future directions are discussed.
