title: Neutral [2]rotaxane host systems that recognise halide anions in aqueous solvent mixtures.
abstract: Four pyridine N-oxide axle containing [2]rotaxanes have been synthesised via an anion templated threading-followed-by-stoppering strategy and shown to be the first examples of neutral interlocked host systems capable of recognising halide anions in aqueous solvent mixtures.
