Molecular shuttle has potential applications in molecular switch, molecular logic gate, information storage and other fields. It is one of the hot spots in the field of supramolecular chemistry. In this paper, the progress of research on light-driven molecular shuttle is reviewed in this paper. The methods of recognizing the position of molecular shuttle driven by light, such as fluorescence spectrum recognition and circular dichroism spectral recognition are introduced emphatically. The new method of constructing optical drive molecular rapide Including directional synthesis of light-driven cyclodextrins [2] and [1] rotaxane molecular shuttles, and examples of optically-driven rotaxane molecular shuttles and light-driven [3] rotaxane molecular shuttles and molecular Shuttle polymers; Illustrates the functional applications of light-driven molecular shuttles: the use of light-driven molecular shuttles to simulate molecular-level logic gates, the energy transfer mechanism in light-driven molecular shuttle systems, and the non-solution state light driven molecular shuttles The future development of molecular shuttle was prospected.
