Cucurbit[ n ]uril‐based rotaxane or pseudorotaxane devices connected to gold electrode surfaces and spherical gold nanoparticles have previously been developed. Herein, we report the preparation and characterization of gold nanorods (GNRs) protected by a hydrophilic cucurbit[7]uril‐based‐pseudorotaxane anchored monolayer. The resulting GNRs decorated with both cucurbit[7]uril‐based pseudorotaxane disulfide and sodium thioctate on their entire surface through covalent S–Au linkages are water‐soluble as well as stable in both solution and the solid state.
