摘要

Glutathione‐capped CuNCs (GSH‐CuNCs) were used in this work to form fluorescent assemblies. This simple approach occurs by introducing organic solvents. Multicolor fluorescence emission assemblies with excellent reversibility were constructed based on aggregation‐induced emission and the solvent effect of GSH‐CuNCs. A possible mechanism, which is based on the size of assemblies and electron transfer, was explored to explain the solvent effects of GSH‐CuNCs. Stimuli‐responsive nanoswitches with excellent reversibility can be controlled by changing the types of organic solvents and the ratio of organic solvent to GSH‐CuNCs aqueous solution. As the CuNCs assemblies exhibit strong, stable, and color‐tunable fluorescence, they are employed as the color conversion materials for recognizing different organic solvents. More information can be found in the Full Paper by J. Hao et al. on page 3545.
