Nitrate Anion Recognition in Organic-Aqueous Solvent Mixtures by a Bis(triazolium)acridine-Containing [2]Rotaxane

摘要

The synthesis of a novel [2]rotaxane host system containing a bis(triazolium)acridine-based axle component is reported. (HNMR)-H-1 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.
