Ionic liquids tethered to a preorganised 1,2-diamide motif for extraction of lanthanides

Author affiliations

Abstract

New preorganised 1,2-diamide functionalised, bidentate ligand-embedded hydrophobic ionic liquids (DAILs) were synthesised, which enabled efficient extraction of lanthanides from an aqueous phase. The selective metal binding ability of the functionalised ionic liquid was examined by NMR, FTIR and a structure optimisation calculation. The selective liquid–liquid extraction behavior with DAILs was demonstrated.
