A Light-Driven Rotaxane Molecular Shuttle with Dual Fluorescence Addresses

A Light-Driven Rotaxane Molecular Shuttle with Dual Fluorescence Addresses

A molecular shuttle containing an α-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 reversib...

description A molecular shuttle containing an α-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.
