✦ Synopsis

A [2]catenane, able to bind π-electron-rich guests inside the macrocyclic components of a [2]catenane. The structure of this [2]catenane, as well as that of a model [2]catenane, have cavity of one of its two macrocyclic components has been designed and synthesized using supramolecular assistance.

been characterized unequivocally by single-crystal X-ray analyses. Furthermore, some of the co-conformational This recognition motif has been exploited to template the formation of a so-called rotacatenane -i.e., a molecule changes associated with these mechanically interlocked molecules in solution have been probed by variable-composed of a dumbbell-shaped component threaded through the cavity of one of the two mechanically interlocked temperature 1 H-NMR spectroscopy.
