Photo-Driven Molecular Shuttles

Molecular shuttle, as a formidable challenge to construct motors and machines of nano-size dimension, have potential applications in areas such as nano-structured functional materials, molecular switches, molecular logic gates, memory devices, and so on. In this paper, the progress in photo-driven molecular shuttles is introduced. Co-conformational identifications of molecular shuttles, like using fluorescence spectra and circular dichroism spectra are mainly generalized. The methodology to construct novel photo-driven molecular shuttles, like the unidirectional synthesis of cyclodextrin 2] rotaxane and 1] rotaxane, rotaxane shuttles driven by light indirectly, 3] rotaxane shuttle and polyrotaxane, is elaborated. The potential functionality of molecular machine in such areas as molecular logic gates, the energy transfer of molecular shuttles, and the properties of molecular shuttles in non-solution media are reviewed, and the future development of molecular machine is prospected.
