DOI: 10.1002/jssc.202100322 The cover picture shows how the enantioselectivity with a chiral MOF of two chiral racemates, limonene and 1‐phenylethanol are influenced by the solvent used for the enantioseparation. When methanol is present in the adsorption phase, an enantioselectivity reversal is observed for 1‐phenylethanol but an enhancement is observed for the corresponding separation of racemic limonene. Chromatograms of the two separations with and without methanol are used to highlight this with each enantiomer peak labelled. The background shows a perspective view of the chiral MOF used in this work and the crystal structures placed above each solvent stream representing a straw, highlight the chiral helical channels present in this MOF.
