A rotaxane host system containing integrated triazole C-H hydrogen bond donors for anion recognition.

Abstract:

Two rotaxanes incorporating a 3,5-bis(triazole)-pyridinium axle component have been prepared using either an anion templated amide condensation or ring closing metathesis (RCM) clipping strategy. The respective yields of interlocked receptor were found to be significantly higher when the RCM clipping synthetic route was used. Proton NMR titration experiments in competitive 1 : 1 CDCl(3)-CD(3)OD solvent media reveal that the rotaxane prepared by the clipping procedure is selective for halide a...
