meso-Tetrakis(4-alkoxyphenyl)porphyrins were generated by condensation of 4-alkoxybenzal- dehydes with pyrrole, followed by reaction with manganese acetate to form nine corresponding complexes. Molecular structures of all synthesized compounds were confirmed by IR, UV, 1H NMR, MS spectra and elemental analysis. Characteristic spectrometric data of IR, UV, 1H NMR related to their structures have been systematically analyzed. Differential scanning calorimetry and polarizing microscope were used to probe the liquid crystal properties of the serial complexes. Eight of the serial complexes were found to exhibit liquid crystal properties. The effects of alkoxy chains, metal ions of complexes and molecular space structure on liquid crystal properties have been investigated.

Key words: manganese complex of porphyrin, spectral analysis, liquid crystal property, synthesis
