Exploiting the 1,2,3‐Triazolium Motif in Anion‐Templated Formation of a Bromide‐Selective Rotaxane Host Assembly

Abstract

Bromide is best: The first [2]rotaxane incorporating the triazolium anion-binding motif is prepared using bromide anion templation. Preliminary anion-binding investigations reveal that the rotaxane exhibits the rare selectivity preference for bromide over chloride ions.
