英文摘要: This project has realized a smart design of using the principle of intercalation of composites into the preparation of functional graphene. Through the special planar and conjugated structures of porphrin and graphene, the functional macromoleculars will be effectively intercalated into the flakes of graphene oxide. A series of new graphene composites will be fabricated by changing the metal centers, the functional groups of porohyrins, and the arrangement modes of porohyrins in the graphene layers to obtain solar power battery, help to select photosensitizers with high efficiency and stability. These researches and results have very important meaning for the development of new functional graphene composites and the application of green environmental energy like solar power.
