Chloride Recognition in Aqueous Media by a Rotaxane Prepared via a New Synthetic Pathway

Abstract

Clip to engage a ring and interlock: The preparation of a novel [2]rotaxane by a new synthetic pathway that exploits anion templation in combination with π–π stacking interactions is described (see scheme). Preliminary anion binding investigations reveal the rotaxane is capable of selectively recognizing chloride in aqueous solvent media in preference to basic oxoanions.
