Abstract

Cucurbit[6]uril-based reversible bistable [2]pseudorotaxanes were designed, synthesized and installed on the surface of mesoporous silica nanoparticles as supramolecular nanovalves. The assembled mechanized silica nanoparticles realize the multistage pH-controlled release of benzotriazole and the potential for reutilization.
