36. This finding is in good agreements with molecular mechanics calculations (AMBER*). In the calculated energetic minimum structure of complex 3@1a the nitrogen atom is centered in the cavity of 1a.
37. At room temperature all complexation/decomplexation processes are fast with respect to the NMR time scale so that only averaged signals of complexed and free substrate are observed.

40. a) We assume that the orange precipitate obtained from the mixture of the solutions of 1a and 12 consists of the clipped rotaxane 12@1a. But up to now we have not been able to grow crystals suitable for a crystal stucture analysis.
