Abstract:

Coordination-based ionic liquids (IL) have attracted extensive fascination in past few years, for their exceptional physical properties and potential applications in green separation, catalysis and electrolytes. Among them, chelate ILs are advantageous due to their enhanced multiple-site chelating interactions between metals and ligands. Based on positions of metallic components in molecules, chelate ILs can be divided into four classes, i.e., cation, anion, cation-anion and neutral chelate ILs. The synthesis, physical properties and applications of chelate ILs were reviewed from recent publications. Present issues, challenges and future research directions were also discussed.

Key words: ionic liquids, preparation, thermodynamic properties, catalysis

摘要:

配位型离子液体在过去一段时间内得到了广泛的关注。其中,螯合型离子液体因其存在多个配位点,因而可以通过螯合作用增强金属与配体的相互作用。根据金属在分子中所处的位置,可以将螯合型离子液体分为4种类型:阳离子螯合型离子液体、阴离子螯合型离子液体、阴阳离子螯合型离子液体和中性螯合型离子液体。对近年来报道的螯合型离子液体的合成、物理性质及其应用进行了综述,阐述了其存在的问题、面临的挑战和今后研究的方向。
