文摘

Through the adsorption/intercalation of cobalt phthalocyanine (CoPc) onto/into graphene oxide (GO) layers, CoPc鈥揋O nanocomposite was prepared via a simple solvent evaporation method driven by the electronic interaction between CoPc and GO. The interaction between GO and CoPc has been studied in detail by various methods. The result suggests that the interaction does not follow a simple donor鈥揳cceptor mode, but, instead, it is complicated two-way process including the transfer of electron from the graphitic domain to the adsorbed/intercalated CoPc, and a feedback from the Co ions through the ligand-like attacking of oxygen functional groups of GO to the central cobalt ions. The obtained structural hybrid materials have potential in the electrochemical detection of the compounded medicine.
