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

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 s...

Description
Summary: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. The synthesis and metal binding ability of a novel 1,2-diamide functionalised ionic liquid system for lanthanide extractions from water is described in this communication.
