Preparation And Characterization Of Asymmetric Zinc Phthalocyanine

As the special structure of phthalocyanine molecule, it has some characteristics of electronic distribution, highly delocalized electronic states, the same bond length of carbon and nitrogen substantially, and structural stability who is not easily deformed,so it has stable physical properties, chemical properties and optical properties and special UV spectrum (B and Q bands).It has a wide range of applications in biomedical, liquid crystal display, aerospace and chemical fields.In this thesis,we can synthesize of4,5-docosyloxy phthalonitrile and4-(4hydroxyphenyl oxy) phthalonitrile, using these two substances as precursors,we can also synthesize asymmetric zinc phthalocyanine. Using the Doping principle, it would be doped with methyl methacrylate,to preparing phthalocyanine polymer. After characterization by melting point test, infrared spectra (IR), fluorescence spectra, ultraviolet-visible spectra (UV-Vis) and nuclear magnetic resonance spectra (NMR), We can characterize these products.
