Synthesis And Properties Of Sulfur-containing Porphyrazines Compounds

Green chemistry method to degrade organic pollutants is a meaningful researchtopic.Imitation light catalytic oxidation process is one kind of green processingmeans.General biology of some metal containing enzymes capable of degradingorganic pollutants. Imitation light catalytic oxidation technology is the simulation ofmetal containing oxidase oxidation degradation of organic pollutants in water.So, Ithas a good development and application prospection.The photocatalytic capability of Sulfur tetraazaphorpyrin metal complexes whichhas an extended delocalized18π-electron conjugated macrocyclic system is betterthan metal-phthalocyanines. It can activate and catalyze H₂O₂and O₂to degrade theorganic pollutants.This paper from the aspects of synthesis and separation of related compounds arediscussed. Synthesis of several novel sulfur-containing tetraazaphorpyrin metalcomplexes, and selective review in the light catalytic reaction system in catalyticoxidation of organic pollutants degradation ability. The main content of this thesisincludes the following three aspects:1.2,3-dicyano-5-hydroxy-1,5-dithiin as precursor, template reaction methodsuccessfully synthesized a new complexes-MgPz（OH-dtn）₄and ZnPz（OH-dtn）₄.2.MNT（n-Bu）2as precursor, template reaction method successfully synthesizedH₂Pz（S-Bu）8and Corrole compouds.3. Rhodamine B and as the model molecular of degradation, When theZnPz（OH-dtn）₄was loaded on the ion-exchange resin （Amberlite CG400） to activatedoxygen for the oxidative degradation of organic compounds.Research indicates that,the compound in a wide pH range showed good catalytic performance.
