Zusammenfassung:A change in geometry is necessary on entry into the capsule: a supramolecular associate approximately 1.8 nm long (see schematic representation), which consists of two halves stabilized by hydrogen bonds, influences the intra‐ and intermolecular interactions of the guest molecules encapsulated. Thus tertiary amides and anilides such as 1, which exist in solution preferably as E rotamers, are fixed in the Z conformation inside the capsule for steric reasons.
