A fluorescent bistable [2]rotaxane molecular switch on SiO2 nanoparticles1. Issue 24 (25th March 2015) - Cao, Zhan-Qi
Abstract A fluorescent bistable [2]rotaxane was immobilized onto the surface of SiO2 nanoparticles through click reaction. The shuttling motion of the macrocycle component was driven by external acid–base stimuli both in solution and on SiO2 nanoparticles, accompanied by visual fluorescence changes.
