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
Six complexes of tetra(4 p decanoyloxyphenyl)porphyrin(TDPPH 2) with Mn(Ⅲ), Fe(Ⅲ), Co(Ⅱ), Ni(Ⅱ), Cu(Ⅱ) and Zn (Ⅱ) have been synthesized in a mixed solvents of CH 2Cl 2 and DMF.

The compounds were characterized by elemental analysis, UV Vis, FTIR photoacoustic spectrometry, 1H NMR and molar conductance measurements. The optical textures of the isotropic liquid crystals of TDPPH 2 and TDPPZn on cooling were observed by polarized light microscope.展开更多
