Dual‐Mode Controlled Self‐Assembly of TiO2 Nanoparticles Through a Cucurbit[8]uril‐Enhanced Radical Cation Dimerization Interaction

The realization of controllable multicomponent self‐assembly through reversible supramolecular interactions is a challenging goal, and is an important strategy for the fabrication of switchable nanomaterials. Herein we show that the self‐assembly of TiO nanoparticles (NP) functionalized with methyl... Full description

description: The realization of controllable multicomponent self‐assembly through reversible supramolecular interactions is a challenging goal, and is an important strategy for the fabrication of switchable nanomaterials. Herein we show that the self‐assembly of TiO nanoparticles (NP) functionalized with methyl viologen can be controlled both by light irradiation and chemical reduction through cucurbit[8]uril‐enhanced radical cation dimerization interactions. Moreover, the controlled assembly and disassembly of this system are accompanied by switchable photocatalytic activity of the TiO NPs, which shows potential application as a novel smart and recyclable photocatalyst. : The self‐assembly of TiO nanoparticles (NPs) functionalized with methyl viologen (MV) can be controlled both by light irradiation and chemical reduction through a cucurbit[8]uril‐enhanced radical cation dimerization interaction. This stimuli‐responsive self‐assembly process can switch the photocatalytic activity of the MV–TiO NPs on and off.
