Transition metal complexes of meso-tetra(4-myristyloxyphenyl)porphyrin TMPPM [M =Mn, Fe, Co, Ni, Cu, Zn; TMPP=mesotetra(4-myristyloxyphenyl)porphyrin] have been synthesized and characterized by means of elemental an...Transition metal complexes of meso-tetra(4-myristyloxyphenyl)porphyrin TMPPM [M =Mn, Fe, Co, Ni, Cu, Zn; TMPP=mesotetra(4-myristyloxyphenyl)porphyrin] have been synthesized and characterized by means of elemental analyses, UV-Vis spectra, infrared photoacoustic spectra, 1H NMR spectra, molar conductance and differential scanning calorimetry(DSC). The ligand and the Zn complex show liquid crystalline behavior. According to the DSC thermogram of the Zn complex, it exhibits a lower phase transition temperature -7.453 ℃ and a wide mesophase temperature span, 77 ℃.展开更多

The structures of compounds were characterized by elemental analysis, UV-Vis, FTIR photoacoustic spectrum, 1H NMR and MS. The domains of stability and the structure of the liquid crystalline phases were determined by optical microscopy, differential scanning calorimetry (DSC). According to the DSC thermogram of compounds, compound(3) exhibits lower phase transition temperature at - 36℃ and a wide mesophase range in 175℃.展开更多
