Abstract

The cover picture shows the calix[6]arene‐based tris(imidazole) ligand coordinated to divalent metal ions. These supramolecular edifices mimic enzyme environments. These funnel complexes present an exchangeable coordination site located in the heart of the hydrophobic cavity of the calixarene. The interplay between the strength of the host−guest noncovalent interactions and the flexibility of the system allows a variety of geometries for the metal complexes, either tetrahedral, tri‐ gonal‐bipyramidal or square‐pyramidal. Details are discussed in the article by O. Reinaud et al. on p. 1817 ff.
