Realization of controllable multi-component self-assembly through reversible supramolecular interactions is a challenging goal, which represents an important strategy for the fabrication of switchable nanomaterials.Herein we show that the self-assembly of TiO2 nanoparticles (NP) functionalized with methyl viologen can be controlled in a dual mode, i.e.light-irradiation and chemical reduction, through cucurbit[8]uril-enhanced radical cation dimerization interaction.Moreover, the controlled assembly and disassembly of this system are accompanied with switchable photocatalytic activity of TiO2 NP, which shows potential application as a novel "smart" and recyclable photocatalyst.
