The Front Cover shows an artistic view of an inclusion complex resulting from the association of dodecanedioyl dichloride and a pillar[5]arene derivative. The latter has been used to prepare a series of pillar[5]arene‐containing [2]rotaxanes under solvent‐free conditions by solid‐to‐solid ball‐milling with various amine reagents. Importantly, [2]rotaxanes difficult or even impossible to prepare in solution are now easily accessible. More information can be found in the Full Paper by J.‐F. Nierengarten et al.
