1. a) Rotaxanes are compounds in which a cyclic component encloses a linear component without covalent bonding between both components. Unthreading of the mechanically bound rings is prevented by sterically effective blocking groups attached to the linear component;

32. Supramolecular complexes are also interesting because they enable, for example, the investigation of electrochemical (L. Echegoyen, P. L. Boulas, M. Gomez-Kaifer, Angew. Chem. 1998, 110, in press; Angew. Chem. Int. Ed. Engl. 1998, 37, in press) or photochemical processes (V. Balzani, Tetrahedron 1992, 48, 10443; V. Ramamurthy, ibid. 1986, 42, 5753) in an environment with a defined geometry. Supramolecular structures can be fixed by irradiation with light (C. Mertesdorf, H. Ringsdorf, J. Stumpe, Liq. Cryst. 1991, 9, 337).

42. The possibility of accomplishing the reverse reaction - that is, the (Z)/ (E) isomerization - either photochemically or thermally was not investigated.
43. The tetraphenylbutane groups probably prevent unthreading only of the 1b rings, since monomeric tetraphenylcyclobutane is rapidly enclosed by 1c[10). The 1b rings stop the 1c rings from wandering.
