Using host-guest chemistries in a biphasic system, a novel supramolecular nanoparticle surfactant (s-NPS) with redox-responsiveness is presented to structure liquids. The in situ assembly/jamming and disassembly/unjamming of s-NPSs at the oil-water interface are reversibly controlled by a switchable redox process, imparting a nanoscale redox-responsiveness, affecting the assemblies on all length scales. "Smart" all-liquid constructs including structured emulsions and programmable liquid devices are easily prepared, showing promising applications in responsive delivery, release, and reaction systems.
采用两相体系中的主客体化学，设计了一种具有氧化还原响应性的新型超分子纳米粒子表面活性剂（s-NPS）来构建液体。s-NPS 在油水界面的原位组装/缠结和解组装/解缠结可通过可切换的氧化还原过程进行可逆控制，赋予纳米级氧化还原响应性，影响所有长度尺度上的组装。“智能”全液体结构包括结构化乳液和可编程液体器件，容易制备，在响应性输送、释放和反应系统中具有广阔的应用前景。
