    • While a number of systems were prepared early on that contained both anion-and cation-binding subunits constrained at remote sites within the same molecular framework, few of these displayed cooperative anion plus cation binding in solution or coupled anion and cation complexation in the solid state. Thus, they are not considered to be bona fide ion-pair receptors. For reviews of these systems, see: (a) Kirkovits, G. J, Shriver, J. A, Gale, P. A, Sessler, J. L. J. Inclusion Phenom.

    • In the CsF complex of 2, the F- ion is symmetrically bound to the four NH groups of the calix[4]pyrrole via four hydrogen bonds at a N⋯F- distance of 2.79 Å, whereas the Cs+ ion is symmetrically encapsulated within the cone-like cavity of the calix[4]pyrrole via π-cation interactions with a distance of 3.39 Å between the Cs+ ion and the centroids of the pyrrole rings. The F- ion interacts with both the Cs+ ion in the same complex and the one in an adjacent complex with separation distances of 3.69 Å and 2.77 Å, respectively
