▎ 摘　　要

We have demonstrated that via nitrene addition, graphene was covalently functionalized by tetraphenylethylene, which is a typical aggregation-induced emission (AIE) molecule with a twisted conformation. The obtained new nanocomposite TPE-C4N3-G-S was characterized by transmission electron microscopy (TEM), fourier transform infrared (IR) spectroscopy, fluorescence spectroscopy, UV-vis, thermo-gravimetric analysis (TGA), and C-13 NMR. The twisted conformation of TPE-C4N3 was effective in improving the solubility and dispersion stability of graphene, and the resulting composite was totally soluble in organic solvents. The resulting product was determined to have one functional group per 48 carbons. In addition, this new type of molecule may open up a new avenue for the synthesis of graphene-based materials and nanodevice fabrications.
