At an elevated temperature, a methylated β-cyclodextrin (β-CD) derivative was self-assembled onto a poly(ethylene glycol) (PEG) chain attached to bulky end groups (slipping), and entrapped through a chemical modification at the end groups (expanding), leading to an interlocked species. The preparation of a loose-fit polyrotaxane composed of β-CD and PEG was demonstrated as the slipping–expanding protocol.
在高温下,甲基化的β-环糊精(β-CD)衍生物在聚乙二醇(PEG)链上自组装,并附着在体积大的端基上(滑动),并通过端基的化学修饰(膨胀)被包裹起来,形成互锁的物质。通过滑动-膨胀方案,制备了由β-CD和PEG组成的松散聚多糖。
