    • 1H 1D spin saturation transfer experiments both at 298 K and 333 K, irradiating the resonances that arise from the protons of the encircled DNP units of the rotaxane. Even at 333 K, we could not observe any change in the intensity of the exchanging resonances for the protons of the free DNP units.

    • We have previously studied host-guest properties of various macrocycles in aqueous solution. Especially we have demonstrated the inclusion complexes (at pH 7) of neutral cucurbit[8]uril (CB[8]) with the two threads 1 4 Cl and 2 2 Cl (Figure 1), leading to the formation of [n]pseudorotaxane-based systems, which underwent reversible conversion between inter- and intramolecular motion triggered by electrochemical stimuli.
