A one-pot synthesis of polyrotaxanes has been developed. The method employs a supramolecular monomer comprising a polymerizable ammonium salt and crown ether, in combination with dynamic ADMet polymerization. Ultimately, highly efficient complexation, polymerization, and end-capping were accomplished in a single operation to yield polyrotaxanes with M(w) up to 19.3 kDa and >80% of the repeat units being complexed.
已开发出一种多轮烷的一锅合成方法。该方法采用包含可聚合铵盐和冠醚的超分子单体,结合动态 ADMet 聚合。最终,在单个操作中实现了高效的络合、聚合和端封,得到了分子量高达 19.3 kDa 且超过 80%的重复单元被络合的多轮烷。
