[反应：合成了含有α-CD大环、偶氮苯单元和两种不同荧光萘酰亚胺单元的分子穿梭物。偶氮苯单元的顺反光异构化导致CD大环在轨道上运动。由于两个终止单元的荧光变化容易调控且完全可逆，分子梭可用作分子存储介质或具有全光输入和输出的开关。
[reaction: see text] A molecular shuttle containing an alpha-CD macrocycle, an azobenzene unit, and two different fluorescent naphthalimide units was synthesized. The cis-trans photoisomerization of the azobenzene unit resulted in the motion of the CD macrocycle on the track. Because of the easy regulation and full reversibility of the fluorescence change of the two stopper units, the molecular shuttle could be used as a molecular storage medium or switch with all-optical inputs and outputs.
