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 CH⋅⋅⋅π interaction between the guest and the capsule is either enhanced or diminished (represented by the color of the guest).
