We report a rotaxane based on a simple urea motif that binds Cl<sup>-</sup> selectively as a separated ion pair with H<sup>+</sup> and reports the anion binding event through a fluorescence switch-on response. The host selectively binds Cl<sup>-</sup> over more basic anions, which deprotonate the framework, and less basic anions, which bind more weakly. The mechanical bond also imparts size selectivity to the ditopic host. ...[more]
