Abstract:UVVis absorption, fluorescence and Raman spectra of tetrakis(4carboxylphenyl)porphyrin (TCPP) in H_2O/CF_3COOH, H_2O/CCl_3COOH and H_2O/CH_3COOH solutions were studied. It was found that TCPP exists as molecular state Nprotonated porphyrin H_8TCPP2+ in H_2O/CCl_3COOH and H_2O/CH_3COOH solutions, but as Jaggregated H_8TCPP~2+ in H_2O/CF_3COOH solution. Raman spectra indicate that the H_8TCPP~2+ molecules in the aggregates have similar arrangements with the Jaggregates of Nprotonated tetrakis(4sulfonatophenyl)porphyrin H_4TSPP~2-.
Keywords:Porphyrin  JAggregate  Raman Spectra  UVVis Absorption Spectra
