A series of cyclodextrin-derived room temperature macromolecular ionic liquids carrying rather low glass transition temperatures of -20 to -40 °C are synthesized via sequential esterification, quaternization, and anion metathesis reactions. In addition to being ionic in nature, they are viscous liquids at room temperature with more fluidic behavior at elevated temperatures. They serve as a solvent for organic dyes or iodine separation via a liquid-liquid extraction approach. This strategy is useful for the development of various sugar (macro)molecule-based functional ionic liquids as well as macromolecular ionic liquids.

聚乙二醇化阴离子衍生的β-环糊精衍生的室温高分子离子液体。

通过顺序酯化，季铵化和阴离子复分解反应，合成了一系列环糊精衍生的室温大分子离子液体，它们的玻璃化转变温度为-20至-40°C。除了本质上是离子性的，它们在室温下还是粘性液体，在高温下具有更多的流体行为。它们用作通过液-液萃取方法分离有机染料或碘的溶剂。此策略对于开发各种基于糖（大分子）分子的功能性离子液体以及大分子离子液体非常有用。
