Hula hoop : The rotary movement of a chromophore‐modified α‐cyclodextrin (α‐CD) was studied in a rotaxane structure attached to a glass substrate. The rotary movement of the α‐CD was demonstrated by defocused wide‐field imaging with total internal reflection fluorescence microscopy. The motion of the α‐CD is suspended in the dry state, whereas a fast rotary movement/rotary vibration is observed in the wet state.
