The synthesis and characterization of 5,10,15,20-tetrakis(4-myristyloxyphenyl) porphyrin and [5,10,15,20-tetrakis(4-myristyloxyphenyl)porphyrin]zinc(II) with long ester chains are reported. The domains of stability and the structure of the liquid crystalline phaseswere determined by optical microscopy and differential scanning calorimetry (DSC). According to theDSC thermogram of the Zn complex, this compound exhibits a phase transition at -7.45 graduate C, lower than that of the ligand and a wide mesophase range at 77graduate C.
