Impact of Threading State on the Mechanics of γ‐Cyclodextrin–Pyrene Gels
Angewandte Chemie, EarlyView.Tuning the threading state of discrete γ‐cyclodextrin (γ‐CD)–pyrene pseudorotaxane crosslinkers controls gel topology and ring mobility. The resulting doubly threaded slide‐ring networks exhibit solvent‐switchable dissipative dynamics, high extensibility, rate‐dependent mechanics, and low hysteresis, revealing how crosslink topology governs macroscopic
