Bis-cation salt complexation by meso-octamethylcalix[4]pyrrole: linking complexes in solution and in the solid state

Claudia Caltagirone, Nathan L. Bill, Dustin E. Gross, Mark E. Light, Jonathan L. Sessler and Philip A. Gale

Pyridinium and imidazolium bis-cations are shown to link calix[4]pyrrole anion complexes both in solution and in the solid state. This is accomplished by binding of the bis-cations to the electron-rich bowl shaped cavities formed by two separate calixpyrrole–anion complexes. These resulting sandwich-type structures provide a new way of organising calix[4]pyrrole anion complexes in space.
