Benzenebistriazole-strapped calix[4]pyrrole: a neutral anion receptor with CH and NH donor groups that exhibits high sulfate binding affinity and selectivity in aqueous solution

Abstract

A calix[4]pyrrole strapped by benzenebistriazole has been prepared as artificial anion binding receptor. This neutral anion receptor shows high sulfate binding affinity and selectivity in aqueous solution. In the solid state, the receptor binds the sulfate anion in a chair-like three-dimensional cavity via multiple N-H and C-H hydrogen bonds.
