Study On Fabrication And Optical Limiting Properties Of Graphene Hybrid Materials Functionalized With Metallophthalocyanines

In this dissertation, three sulfonated metallophthalocyanine compounds were synthesized by solid phase method, VOTsPc, InClTsPc and FeClTsPc. we synthesized graphene oxide (GO) through the Hummers method, and then accepted the graphene modified by Phthalic Diglycol Diacrylate (PDDA). As this thin composite films with alternating layers containing sulfonated metallophthalocyanine and graphene modified by PDDA have been prepared by the electrostatic self-assembly technique. During the process, the films were characterized by UV-Vis spectroscopy, showing the adsorption process was regular, and the number of bilayers was controllable.Besides, the metallophthalocyanine and the grapheme nanoparticles can be easily seen by atomic force microscopy. At last the composite films were measured by using4f coherent imaging technique.Tetra-amine phthalocyanine of copper was synthesized by liquid phase method, we synthesized GO through the Hummers method, and then accepted the graphene modified by carboxyl group. At last covalent attachment of graphene modified by carboxyl group to tetra-amine phthalocyanine of copper. As this macromolecules functional initiator could get from the composites. Styrene as monomer, were successfully synthesized corresponding polymer by atom transfer radical polymerization (ATRP). And the polymer was measured by using Z-scan technique.
