| Research Abstract |
Biological molecular motors such as muscle fibers, flagella and cilia are precisely designed in nature, and are reminiscent of microscale electronic and mechanical devices. Inspired by direct observations of rotary molecular motor systems, some researchers have tried to directly observe artificial molecular motors. On the contrary, even smaller artificial molecular motors are extremely difficult to see, and thus, additional visualization techniques are necessary to observe rotational behavior. Rotaxane has a suitable structure to construct molecular motors. Herein we observe a single rotaxane molecule based onα-cyclodextrin(α-CD) attached to a fluorescence probe on glass substrates and estimate the rotary movement ofα-CD as a rotor, which was measured by total internal reflection fluorescence microscopy(TIRFM). Herein, we observe the rotary movement of
