Bis-triazolium containing macrocycles, pseudorotaxanes and interlocked structures for anion recognition

Abstract:

Two bis-triazole macrocycles were prepared by the copper(i)-catalysed azide alkyne cycloaddition of a bis-azide and 1,6-heptadiyne or 1,3-diethynylbenzene. Upon alkylation of one of these to give the dicationic bis-triazolium cycle, a potent receptor was generated which was demonstrated to be selective for sulfate. Two acyclic bis-triazolium receptors were also synthesized and the halide anion recognition properties of these systems investigated, as well as their ability to form anion templat...
