The fourier transform infrared photoacoustic spectra ofmeso-tetra-(4-lauroyloxyphenyl)porphyrin(TLPPH2) and its complexes with Mn (Ⅲ)、Fe (Ⅲ)、Co (Ⅱ)、 Ni (Ⅱ)、Cu (Ⅱ) and Zn (Ⅱ) in the range of 3600～190 cm-1 we...The fourier transform infrared photoacoustic spectra ofmeso-tetra-(4-lauroyloxyphenyl)porphyrin(TLPPH2) and its complexes with Mn (Ⅲ)、Fe (Ⅲ)、Co (Ⅱ)、 Ni (Ⅱ)、Cu (Ⅱ) and Zn (Ⅱ) in the range of 3600～190 cm-1 were measured and investigated. The bands at 3318 and 968 cm-1 of TLPPH2 are due to the N—H stretching and in-plane and out of plane bending vibration of the pyrrole groups. All these bands disappear upon complex formation. The vibration coupling between the M—N stretching and the porphyrin ring deformation appears at 250 cm-1. Metal sensitive bands were found at 1354、1018、983、796、736、632、231 cm-1.展开更多

The equilibrium constants of the aggregation of the metal porphyrin and the equilibrium constant of the π\|π coordination with phenothoroline have been measured by using UV\|Vis titration method. The results show that the equilibrium constants decrease in the order of K \-\{CuP\}> K \-\{NiP\}> K \-\{ZnP\}. The vitro anti\|tumor activities of the dibutyltin(Ⅳ) metal porphyrinate has some relation with the ability of aggregation and coordination with ligand of the metal porphyrin.展开更多
