46_45b/2007Inside Cover: Guest and Ligand Behavior in Zinc-Seamed Pyrogallol[4]arene Molecular Capsules (Angew. Chem. Int. Ed. 45/2007)

A guest of choice confined within an octanuclear zinc-seamed pyrogallol[4]arene capsule (light green Zn, red O, black C) can act as a reporter for electronic communication between the exterior and interior of the capsule. As Atwood and co-workers report in their Communication on page 8601 ff., by interchanging ligands (represented by blue and dark green balls) and concomitantly varying electron donation to the metal centers, a C-H···π interaction between the guest and the capsule is either enhanced or diminished (represented by the color of the guest).
