title: Anion recognition in water by a rotaxane containing a secondary rim functionalised cyclodextrin stoppered axle.
abstract: The synthesis of a water soluble [2]rotaxane is reported using hydrophilic secondary rim functionalised permethylated β-cyclodextrin derivatives as the axle stopper groups. The rotaxane recognises halide anions in pure water with impressive selectivity over sulfate.
