Graphene/acridine(G-Acr) hybrid structures were synthesized through covalent functionalization of graphene oxide with 9-(4- aminophenyl)acridine(APA) and its derivatives.The G-Acr hybrids were characterized by Fourier transform infrared spectroscopy, ultraviolet-visible spectrophotometry,thermal gravimetric analysis and Raman spectroscopy.X-ray photoelectron spectroscopy confirms that the binding energies of APA and its derivatives shifted to higher values,revealing pronounced charge transfer at the interface of graphene and organic molecules.
