A new method for the preparation of graphene has been developed via porphyrin exfoliation of graphite in NMP. The exfoliation, which follows the intercalation of organic ammonium ions, is based on the π-π interaction between graphene and porphyrins. The graphene sheets prepared by this method show u...

Summary:A new method for the preparation of graphene has been developed via porphyrin exfoliation of graphite in NMP. The exfoliation, which follows the intercalation of organic ammonium ions, is based on the π-π interaction between graphene and porphyrins. The graphene sheets prepared by this method show undisturbed sp 2 carbon networks. A simple and efficient method for the preparation of graphene has been developed via organic ammonium intercalation and porphyrin exfoliation of graphite in NMP. The graphene sheets have undisturbed sp 2 carbon networks.
