Inside Cover: A Modulator‐Induced Defect‐Formation Strategy to Hierarchically Porous Metal–Organic Frameworks with High Stability (Angew. Chem. Int. Ed. 2/2017)

Pore size expansion and framework stability are two crucial issues, but are rarely addressed simultaneously in a single metal–organic framework (MOFs). H.-L. Jiang and G. Cai show in their Communication on page 567 ff. that a versatile modulator-induced defect-formation strategy allows the preparation of hierarchically porous MOFs (HP-MOFs) with high stability and tailorable pore features, which enable HP-MOFs to be important porous platforms for applications involving large molecules, especially in catalysis.
