Two large and five small rings interlock to give the [7]catenane depicted on the right. Every potential π‐donor and π‐acceptor recognition site within this molecule is utilized. Only the application of high pressure (12 kbar) made possible the efficient assembly of this exotic molecular compound, for which a solid‐state structure was obtained by X‐ray crystallography.
