Abstract

Modification of the guest polymer ends efficiently and substantially decreases the density of the threaded rings. The minimized ring density drastically facilitates chain sliding through the cross-links in polyrotaxane gels. This molecular design is like regulating the “pressure” of the rings confined in the interlocked architecture, which counteracts the sliding.
