Inside Back Cover: Synthesis of a pH‐Sensitive Hetero[4]Rotaxane Molecular Machine that Combines [c2]Daisy and [2]Rotaxane Arrangements (Chem. Eur. J. 20/2016)

Abstract

Molecular muscles: The self‐sorting strategy between a naked dibenzo‐24‐crown‐8 (DB24C8), a DB24C8‐based hermaphrodite molecule, and a molecular axle that contains both an ammonium or an anilinium template allows for the efficient synthesis of a hetero[4]rotaxane molecular machine. Deprotonation of the anilinium stations allows shuttling of the DB24C8 units along the axle, which is linked to the daisy scaffold (see figure). More information can be found in the Full Paper by F. Coutrot et al. on page 6837 ff.
