Acyclic pyrrole-based anion receptors: design, synthesis, and anion-binding properties

Author affiliations

Abstract

A series of novel, acyclic pyrrole-based anion receptors is described that bind nitrite and carboxylate anions with good selectivity in dichloroethane solution. These systems, which are based on pyridine 2,6-dicarboxamides, also bind cyanide anions weakly. Control systems, incorporating a benzene-1,3-dicarboxamide spacer or wherein the connectivity of the amide linkage is “reversed”, either failed to act as effective anion receptors or displayed very different selectivities.
