Copper and zinc work in tandem in a metal-mediated click reaction that is promoted by the presence of more than one metal in a ditopic macrocycle. The successful formation of a triazole by alkyne–azide cyclization in the pocket of a macrobicyclic phenanthroline-strapped porphyrin generates a rotaxane in which the metal bound in the porphyrin controls the position of the axle. The cover picture illustrates the joint effort of the Japanese and French groups in this scientific investigation and cultural exchange. More information can be found in the Communication by T. Hayashi, J. Weiss et al. (DOI: 10.1002/chem.201702553).
