Inside Back Cover: Directing the Morphology, Packing, and Properties of Chiral Metal–Organic Frameworks by Cation Exchange (Angew. Chem. Int. Ed. 34/2022)

Abstract

Predicting crystal morphologies is challenging because of the many factors influencing their growth. Dan Oron, Michal Lahav, Milko E. van der Boom, and co-workers demonstrate in their Research Article (e202205238) how metal cation exchange in metal–organic frameworks (MOFs) results in a series of chiral crystals having a similar morphology, packing, and a rare space group (P622). The fact that the crystals maintain their morphology facilitates a quantitative comparison of their optical and magnetic properties. The metal cation exchange is likely to be mediated by differently sized nanochannels.
