Synthesis, Characterization Of Sulfur-containing Dinuclear Porphyrazines And Sulfur-containing Corrolazine

Organic pollutants have been a “hard nut” to crack as an important role in theincreasingly serious environmental problems. The porphyrin compounds, which is agreen and efficient catalyst in degradation of organic pollutants. Thus, to crack that“hard nut” is to find an efficientive porphyrazine catalyst with high selectivity andhigh stability, tha’s a very meaningful research to the area of green chemical catalytic.To improved the electronic functions of the porphyrin structure. We adjusted thestructure of our porphyrin to systhesis the H4Pz2（S-Bu）12and the porphyrazineHCO（S-Bu）₈. And we also synthesized a silica shell magnetic nanoparticles as an loadcarrier for the metalloporphyrin, then a preliminary exploried degradationexperiments wea taken. A new mechanism of degradation catslysted by H₂Pz（S-Bu）₈was verificated by us.The main work of this paper is summarized as the following parts:1. The precursors MNT（CH3）2and TCDT were taken to obtained twomonocyclic structures of low symmetrical porphyrazine, respectively the AABB typeof MeS4Pz and A3B-type porphyrazine of MeS6Pz. And then were well characterizedby1H NMR, MALDI-TOF MS and UV-Vis spectrum, ect.2. MNT（Bu）2and1,2,4,5-benzenetetracarbonitrile with the molar ratio of7:1bymagnesium method to obtain the objective product: H4Pz2（S-Bu）12. Then the relatedstructure of the products were well characterized by1H NMR, MALDI-TOF MS andUV-Vis spectrum, ect.3. Use the H₂Pz （S-Bu）₈as a raw material, adding an excess of phosphorustribromide in pyridine, after an occurrence ring condensation reaction we get thetarget product HCO（S-Bu）₈. A series of characterization ware taken to verify itsstructure.4. A green chemical catalysis ZnPz（n-Bu）₈O’s catalytic performance underdifferent conditions were taken. And then we verified a new mechanism of degradation of our catalysis H₂Pz （n-Bu）₈.5. We prepared a silica shell magnetic nanoparticles Fe₃O₄@SiO₂by using themicroemulsion method, and then carry our CoPz （S-Bu） on it to get a compositecatalyst Fe₃O₄@SiO₂-CoPz （S-Bu）₈, and initially explored the catalyst degradation ofit.
