In our current work, we discovered N-triflimide (NTf)-based zwitterionic ionic liquids (ZILs) exhibiting LCST phase transitions in water and showed an ability to further fine tune their structure to afford N-pentafluoroethylsulfonimide (NPf)-based ZILs displaying T_c values attractive for potential applications. This report is, to the best of our knowledge, the first one on both NTf- and NPf-based ZILs as small-molecule thermoresponsive materials for which their mixing with and separation from water triggered by changes in temperature were shown to be fully reversible.

用于发现 LCST 型热响应材料的两性离子盐的结构微调

在我们目前的工作中，我们发现基于N-三氟甲磺酸 (NTf) 的两性离子液体 (ZIL) 在水中表现出 LCST 相变，并显示出进一步微调其结构以提供基于N-五氟乙基磺酰亚胺 (NPf) 的 ZIL，显示T _c值对潜在应用有吸引力。据我们所知，这份报告是第一个关于 NTf 和 NPf 基 ZILs 作为小分子热响应材料的报告，它们与水的混合和分离由温度变化引发的水被证明是完全可逆的。
