Oligo(aryl-triazole)s CH⋯Cl− interactions guide chloride efficient and selective transmembrane transport

Abstract

A series of oligo(aryl-triazole)s (compounds 1–8) have been synthesized and served as transmembrane anion transporters by only CH⋯Cl⁻ interactions. This work confirms their role in the activity of anion transport. By changing the lipophilicity and anion affinity of the compounds, efficient anion transport with remarkable Cl⁻vs. HCO₃⁻ selectivity was achieved.
