A pseudorotaxane containing cucurbituril (as a molecular ‘bead’) threaded on fluorenyltriamine (as a ‘string’) behaves as a fluorescent, reversible molecular switch. The switching of the molecular bead from one site to the other site on the ‘string’ induced by pH change is easily detected by change in color and fluorescence.
