【Abstract】 Six complexes of tetra(4 n octanoyloxyphenyl)porphyins with Mn(Ⅲ), Fe(Ⅲ), Co(Ⅱ), Ni(Ⅱ) , Cu(Ⅱ) and Zn(Ⅱ) have been synthesized in mixed solvents CH 2Cl 2+DMF. The complexes were determined by elemental analysis, UV Vis, FTIR photoacoustic spectrum, 1H NMR and molar conductivity measurement. The domains of stability and the structure of the liquid crystalline phases are determined by optical microscopy and differential scanning calorimerials(DSC). The fourier transform infrared photoacoustic spectra of TDPPH 2 and its complexes in the range of 3 600—190 cm -1 were measured and investigated. [WT5HZ]更多还原
