主　　题：amphiphilic graphene 5,6-diaminopyrazine-2,3-dicarbonitrile cyclization reaction 

摘      要：A simple and effective method for the preparation of amphiphilic graphene(AG)is presented under an organic solvent-free synthetic *** synthetic route first involves a cyclization reaction between carboxylic groups on graphene oxide and the amino groups on 5,6-diaminopyrazine-2,3-dicarbonitrile,and subsequent reduction by *** of UV-vis spectroscopy,Fourier transformed infrared spectroscopy(FT-IR),X-ray photoelectron spectroscopy(XPS),thermogravimetric analysis(TGA)and Raman spectroscopy have confirmed that the covalent functionalization of graphene can be achieved through the formation of imidazo[4,5-b]pyrazine on the graphene *** a result,AG can be successfully dispersed in water and common organic *** work successfully provides a facile and efficient way to fabricate AG and may extend the potential applications of graphene-based materials in nanoelectronic devices,polymer fillers and biological field.
