A photoresponsive system where structure formation is coupled to catalytic activity is presented. The observed catalytic activity is reliant on intermolecular cooperative effects that are present when amphiphiles assemble into vesicular structures. Photoresponsive units within the amphiphilic pre-catalysts allow for switching between assembled and disassembled states, thereby modulating the catalytic activity. The ability to reversibly form cooperative catalysts within a dynamic self-assembled system represents a conceptually new tool for the design of complex artificial systems in water.
本文提出了一种将结构形成与催化活性偶联的光响应体系。所观察到的催化活性依赖于两亲分子组装成囊泡结构时存在的分子间协同效应。两亲性前催化剂中的光响应单元允许在组装和去组装状态之间切换，从而调节催化活性。在动态自组装体系中可逆地形成协同催化剂的能力为设计水中复杂人工体系提供了一种新概念工具。
