Abstract

original image

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.
