Symthesis And Characterication Of Perplayrin Compounds

Porphyrin is a general term of the homologue and derivative of porphyrin withsubstituting groups at the outside ring. When two portons at inside ring are displacedby the metal ion, metalloporphyrins is made up. Since the porphyrin and its metalcomplexes have a special structure and properties, they play an important role inanalytical chemistry, functional materials, molecule identification and photo-electronconversions fields. Carboxyl porphyrin is an important water-soluble porphyrins, theyhave important applications in exploring the mechanism of photosynthesis andincreasing efficiency of photosynthesis.β-substituted porphyrin and its metalcomplexes have been used in catalysis, biological activity and function of materials.Cooperating with previous work in our workshop, the mechanism of interfaceelectron-transfer were studied by different porphyrin modified electrode. In order toinvestigate and reveal the electron and ion transfer in organism, metalloporphyrinswere applied at Liquid/Liquid interface to stimulate the basic model of biologicmembrane. A series of differentβ-substituent with porphyrins and metalloporphyrinswere synthesized.The thesie is composed of four chapters as follows:ChapteChapter I: IntroductionA systematic review was given on synthesis characterization and their applicationof porphyrin and metalloporphyrins.Chapter II: Study on synthesis and spectral properties of a series ofcarboxylphenylporphyrin.Carboxylphenylporphyrin were prepared by Adler method. Their structures havebeen demonstrated by UV-vis, IR and 1HNMR.Chapter III: Study on synthesis and spectral properties ofβ-nitro-phenylporphyrinsTheβ-nitro-porphyrin metal complexes was synthesized by one-spot method withconcentrated sulfuric acid / trifluoroacetic acid removaling the metal ions. The structureof the compounds were characterized by IR, UV-vis and 1HNMR. ChapteChapter IV: Study on synthesis and spectral properties ofβ-Formyl- tetraphenylporphyrinand metalloporphyrinsWith tetraphenylporphyrin as the starting material, copper porphyrin was prepared. then afterβ-Formyl-tetraphenylporphyrin were synthesized by a new simple one-spot method with Vilsmrierformylation reaction and removaling the metal ions by the combination of concentratedsulfuric acid and ultrasonic, further synthesis ofβ-formyl tetraphenylporphyrin nickel, copper,zinc complex.The structure of the compounds were characterized by IR, UV-vis and 1HNMR.Keywords:porphyrin；metalloporphyrins；β-substituted porphyrin；synthesis；characterization.
