A novel molecular recognition motif was built between a selenium-containing pillar[5]arene and a pyridinium bromide salt in water. Furthermore, a supramolecular amphiphile based on this new host–guest recognition motif with redox-responsiveness was fabricated and applied in the controlled release of small molecules.

含硒柱[5]芳烃基的主客体识别作用制备的氧化还原反应性超分子两亲物

在水中含硒的柱[5]芳烃和溴化吡啶鎓盐之间建立了一个新的分子识别基序。此外，基于这种新的具有氧化还原反应的宿主-客体识别基序的超分子两亲分子被制备并应用于小分子的控制释放。
