A Photo-driven Molecular Abacus with Fluorescence Codes Qu Dahui, Wang Qiaochun, Ren Jun, Tian He (Institute of Fine Chemicals , East China University of Science & Technology, Shanghai 200237) Abstract The research of the molecular machine has attracted many chemists because of its potential application value in information storage. The molecular abacus with two different fluorescences (codes), which is a rotaxane employing two different luminophores as the stoppers and a cyclodextrin ring as the abacus ring, can be introduced to perform shuttling motion between two different recognition sites in response to external optical stimuli.
