    • Other forces, e.g. ion-dipole interactions, may play a role. However, none of the dipoles in the cavity walls are directed with the negative partial charge toward the encapsulated cation; rather, they are tangential to the capsule walls. Therefore, we believe these interactions to be small and the cation-π interaction to be the major contribution.
