We developed a covalent functionalization chemistry for pristine graphene using the reactive species of perfluorophenyl nitrene. Generated from the thermal or photochemical activation of perfluorophenyl azides (PFPAs), perfluorophenyl nitrene can produce significantly enhanced bimolecular reactions with graphene leading to covalent adduct formation. Therefore, treating pristine graphene with PFPAs renders graphene soluble in organic or aqueous solutions. In this talk, we discuss the application of the PFPA chemistry to the synthesis of hybrid materials of graphene and nanoparticles. Irradiating a solution of pristine graphene in the presence of PFPA-functionalized nanoparticles covalently attached the nanoparticles to graphene. The hybrid materials are characterized by IR, TEM, XPS, Raman. The application of this method will be elaborated.
