Abstract


Phthalocyanine compounds wih their 18πelectronic delocalization of intense electronic interction in macrocycle and intense transition in visible region display peculiar photo-eleetrical, thermal and chemical characters.As molecular-functional materials,compounds of phthalocyanine are widely used in advanceded science and technology field,which has attracted more and more interest of chemists and physicists in the world. But their research and application are limited because their poor dissolution in solvents and hard to be made film.Therefore the design and synthesis of new dissolubility phthalocyanine compounds to meet different applications have attracted many boffins.The paper focus on that some dissolubility phthalocyanine compounds are synthesized,and the configuration and properties of them are researched.The paper consists of three chapters. In the first chapter, three kinds ofβ-tetraalkyloxy zinc phthalocyanines and oneα-tetralkoxy zinc phthalocyanines are synthesized by using 4-nitrophthalonitrile and phthalic anhydride as staring materials respective. We discuss the reaction temperature and reaction time which can influence the yield of per-phthalocyanines. The most optimumreaction conditions are determined.The yields are enhancedIn chapter two, hydroxyphthalocyanines were received through the hydrolysis of the alkyloxy zinc phthalocyanines in assistance of microwave assistans and the complexes have been characterized.Their hydrogen bond and aggregation were studied by the FTIR and UV.In the third chapter, novel electron-withdrawing fluorinated ligand and its tetrakisβ-4- （1,1,2,2, 3,3,4,4-Octfluoropentyloxy） phthalocyaninatometal complexes have been prepared. Electron- withdrawing fluorine atoms on pentyloxy at the peripheral sites of the blue-green phthalocyanines increase the solubility of these compound. The structures of the target compounds were confirmed using elemental analysis, UV/vis, FT-IR, 1H NMR, and MS spectral date. Spectroelectrochemical measurements confirm that the diminished trend observed for the△E1/20 value of these phthalocy- anines is in good agreement with the red shift of their Q band.
