We propose a simple but efficient, rapid, and quantitative ion-responsive micelle system based on counter-anion exchange of a surfactant with an imidazolium unit. The ion-exchange reaction results in the amphiphilic-to-hydrophobic transition of the imidazolium salt, leading to the destruction of the micelles, which has been successfully applied to controlled release and emulsification. The proposed design offers a novel alternative stimulus to control these smart physical aggregates besides pH, temperature and light-with extra advantages. Our finding greatly benefits both fundamental research and industry.
我们提出了一种基于具有咪唑鎓单元的表面活性剂的抗衡阴离子交换的简单但高效、快速且定量的离子响应胶束系统。离子交换反应导致咪唑鎓盐从两亲性转变为疏水性，从而导致胶束的破坏，这已成功应用于控释和乳化。除了pH、温度和光之外，所提出的设计提供了一种控制这些智能物理聚集体的新型替代刺激因素，具有额外的优势。我们的发现对基础研究和工业都大有裨益。
