一个原型的表面活性剂系统的开发，具有独特的功能，它可以切换之间的聚集，两亲性状态和非聚集，非两亲性状态，使用外部刺激。这种可切换的表面活性剂系统使用可逆形成的动态共价键的pH值和温度触发的开/关自组装的胶束聚集体之间的平衡的可逆位移和它们的两亲性对应物。在控制释放系统中的应用的潜力是通过可逆的吸收和释放的有机染料在水介质中显示。
A prototype surfactant system was developed-with the unique feature that it can be switched between an aggregated, amphiphilic state and a nonaggregated, nonamphiphilic state using external stimuli. This switchable surfactant system uses the reversible formation of a dynamic covalent bond for pH- and temperature-triggered on/off seff-assembly of micellar aggregates by reversible displacement of the equilibrium between nonamphiphilic building blocks and their amphiphilic counterparts. The potential for application in controlled-release systems is shown by reversible uptake and release of an organic dye in aqueous media.
