Targeted Manipulation of Metal-Organic Frameworks To Direct Sorption Properties

Metal–organic frameworks are promising materials for manifold applications. This Minireview highlights approaches for the fine‐tuning of specific sorption properties (e.g. capacity, selectivity, and breathing behavior) of this interesting class of materials. Central aspects covered are the control over the crystal morphology, the targeted tuning of sorption properties by judicious choice of metal centers and linkers, and the preparation of host–guest systems. We want to introduce the reader to these topics on the basis of the manipulation of a handful of outstanding prototypical metal–organic frameworks. Get adjusted! The sorption properties of metal–organic frameworks (MOFs) can be modified in manifold different ways. Linker functionalization, metal exchange, solid‐solution approaches, the formation of host–guest complexes, or control over the crystal morphology are the toolkit to tune pore space and function of the next generation of adsorbents (see figure). These methods are highlighted by examples of prominent MOF classes.
