A covalently‐linked resorcinarene‐based capsule was synthesized by means of a ring‐closing olefin metathesis reaction. The size and dimensions of the wide cavity were contracted by metal coordination. Demetallation restores the cavity shape. The cover artwork illustrates that the reversible shape changes of the internal cavity tune the guest selectivity in shape. More information can be found in the Full Paper by T. Haino et al. on page 5810.
