Exploiting the 1,2,3-triazolium motif in anion-templated formation of a bromide-selective rotaxane host assembly.
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.
