The fabrication of supramolecular amphiphiles by the host–guest interactions between macrocycles and surfactants is an effective method to improve the physical and chemical properties of amphiphiles. However, as far as we know, lowering the critical micelle concentration of anionic surfactant by the complexation of macrocyclic host is scarcely studied. In this work, we systematically studied the host–guest interactions between calixpyridinium and four select anionic bola surfactants. Only congo red that has a conjugated linker could assemble into supramolecular amphiphile with calixpyridinium accompanied by a decreased critical micelle concentration. As a result, the pK_a value of congo red shifted significantly. Moreover, the calixpyridinium–congo red supramolecular amphiphilic assembly exhibited a valuable visible-light response for the complete photodegradation of congo red.

通过大环和表面活性剂之间的主客体相互作用制备超分子两亲物是改善两亲物物理和化学性质的有效方法。然而，据我们所知，通过大环主体络合来降低阴离子表面活性剂的临界胶束浓度的研究很少。在这项工作中，我们系统地研究了杯吡啶鎓和四种精选的阴离子博拉表面活性剂之间的主客体相互作用。只有具有共轭接头的刚果红才能组装成具有杯吡啶鎓的超分子两亲物，同时临界胶束浓度降低。因此，p K _a刚果红的价值发生了显着变化。此外，杯吡啶鎓-刚果红超分子两亲性组装体对刚果红的完全光降解表现出有价值的可见光响应。
