Wurster's crown ligands

Abstract

Wurster's crown ligands comprise a macrocyclic ligand such as a crown ether in which a hetero atom is substituted with a 1,4-phenylenediamine group. The phenylenediamine group is covalently bound to the macrocyclic ligand by one or both of the amine nitrogens, the amine nitrogen thereby substituting for the hetero atom of the macrocyclic ligand. The resulting compounds are redox active. Methods of making and using the compounds are also disclosed.
