Abstract: Tetra-(4-n-lauryloxyphenyl)porphyrin and its complexes of Mn(Ⅲ), Fe(Ⅲ), Co(Ⅱ), Ni(Ⅱ), Cu(Ⅱ) and Zn(Ⅱ) have been synthesized. The compounds were determined and measured by elemental analysis, UV-Vis, FTIR photoacoustic spectrum, 1HNMR and molar conductivity. The Fourier transform infrared photoacoustic of TLPPH2 and its complexes in the range of 3 600-190cm-1 were measured and investigated. The vibration coupling between the M-N stretching and the porphyrin ring deformation appears at 250.0cm-1. The band at 320cm-1 is due to M-Cl stretching vibration. Metal sensitive bands were found at~1352, ~1018, ~993, ~800 and 231cm-1. The stability and the structure of the liquid crystalline phases are examined by optical microscopy and differential scanning calorimetry(DSC). Zn complex exhibits lower phase transition temperature at-50.67 ℃ and wide mesophase range at 143 ℃.
