A Fluorescent Ditopic Rotaxane Ion‐Pair Host

We report a rotaxane based on a simple urea motif that binds Cl(−) selectively as a separated ion pair with H(+) and reports the anion binding event through a fluorescence switch‐on response. The host selectively binds Cl(−) over more basic anions, which deprotonate the framework, and less basic ani...

description We report a rotaxane based on a simple urea motif that binds Cl(−) selectively as a separated ion pair with H(+) and reports the anion binding event through a fluorescence switch‐on response. The host selectively binds Cl(−) 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.
