On page 1117 , Yuval Vidavsky, Suwon Bae, and Meredith N. Silberstein describe a method to control the mechanical properties of a metal‐ligand crosslinked polymer by modulating these interactions. Copper(II) is used to generate covalent‐like crosslinks in a stretchable acrylic polymer, resulting in increased stiffness and strength and reduced ductility. Coordination of the copper cations with different ligands allows control of the dynamic nature of the crosslinking interactions to regulate solubility, solid state mechanical properties, and to impart self‐healing behavior. This coordination also changes the color of the polymer. From right to left, this cover shows a block of this polymer as it is exposed to hydrochloric acid. (DOI: 10.1002/pola.28994 )
