摘要

A lockable as well as double INHIBIT logic gate based on a [2]rotaxane employing configuration and fluorescence changes has been demonstrated (see figure). Importantly, the output "0" and "1" states of the current logic circuits represent several different supramolecular configurations. The photoisomerization process is completely reversible, making the shuttling motions of the cyclodextrin ring repeatable and accompanied by a reversible florescence signal.
