A fluorescent ditopic rotaxane Ion-Pair host

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 fluorescent switch-on response. The host selectively binds Cl- over more basic anions, which deprotonate the framework and less basic anions that bind more weakly. The mechanical bond imparts size selectivity which alters the relative preferences for larger anions.

Abstract

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 fluorescent switch-on response. The host selectively binds Cl- over more basic anions, which deprotonate the framework and less basic anions that bind more weakly. The mechanical bond imparts size selectivity which alters the relative preferences for larger anions.
