A pyrrole-containing cleft-type halogen bonding receptor for oxoanion recognition and sensing in aqueous solvent media†
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.
