| Abstract: | The synthesis of a novel [2]rotaxane host system containing a bis(triazolium)acridine‐based axle component is reported. 1H NMR anion‐binding titrations reveal that the rotaxane is able to recognise selectively the NO3? anion over a range of more basic oxoanions (AcO?, HCO3? and H2PO4?) in a competitive organic–aqueous solvent mixture. |
