Abstract: A series of iron(Ⅲ) meso-tetrakis(4-alkoxyphenyl)porphyrin chloride were synthesized, seven of which were new compounds. Molecular structures of all synthesized compounds were confirmed by IR, UV, 1H NMR, MS spectra and elemental analysis. Differential scanning calorimetry and polarizing microscope(PM) were used to probe the liquid crystal properties of the serial compounds. Eight compounds were found to exhibit liquid crystal(LC) properties, which behaved the single-change liquid crystals or the enantiotropic liquid crystals. Under PM, the LC texture was observed and filamentary optical one was displayed. The effects of alkoxy chains, metal ions of complexes and molecular space structure on liquid crystal properties were investigated. Verifying the (μ-oxy)bis[meso-tetrakis(4-alkoxyphenyl)porphyrin iron(Ⅲ)] and iron(Ⅲ) meso-tetrakis(4-alkoxyphenyl) porphyrin chloride could convert mutually in the adverse reaction by fluorescence spectrum.
