Sodium Copper Chlorophyll And The Organized Molecular Combination Of The Interaction

1. The Effects of Sodium Copper Chlorophyllin on the Structural Characters of CTAB MicellesThe effects of Sodium Copper Chlorophyllin(SCC) on the first critical micelle concentration (cmc₁) and the second critical micelle concentration (cmc₂) of cationic surfactant Hexadecyltrimethylammonium bromide (CTAB) was studied by the methods of conductivity and fluorescence spectra. The aggregation number of CTAB micelles was studied by the methods of the steady state fluorescence . The results show that with the increasing SCC concentration, cmc₁ and cmc₂ of CTAB micelle both decrease, whereas the aggregation number of CTAB micelles increases, the above results may be related to the interaction between SCC and CTAB.2. Sodiun Copper Chlorophyllin self-organization in CTAB aggregatesElectronic absorption spectra, fluorescence spectra and NMR technique were used to study Sodiun Copper Chlorophyllin(SCC) aggregation in CTAB micelles with different microstructures and microenviroments. The studies showed that SCC can exhibit J-aggregation in CTAB micelle with a new absorption spectra at about 670nm. Compared with short-chain cosurfactant and hydrophobic cosurfactant ,medium-chain cosurfactant was favor to SCC dimer, but SCC dimer converted to monomer gradually with increasing the content of medium-chain cosurfactant in CTAB aggregation. A larger absorption of SCC dimer at 670nm was observed in neutral aqueous solution. Radiation is not favor to SCC dimer.3. Direct photolysis of Sodiun Copper Chlorophyllin in CTAB aggregatesThe photolysis of SCC by visible light in different media had been studied. The results suggested that the photolysis of SCC occurred under irradiation with UV-lamp(mecury lamp, 125W) in water, H₂O/C₂H₅OH mixed solution and CTAB aggregates. The photolysis reations of SCC in those media were all in accordance with first-order law. The photolysis rates of SCC in CTAB aggregates were lower than that in water, which may be related with the changes of the polarity of the microenviroment of SCC and the...
