Abstract

The synthesis and anion binding properties of a novel pyrrole-containing dicationic halogen bonding (XB) motif is described. When incorporated into an acyclic cleft-type receptor, rare selectivity for tetrahedral oxoanions (H₂PO₄⁻ and SO₄²⁻) over halides is observed in aqueous solvent media.
