| Abstract: | A series of novel μ-oxo-bismeso-tetrakis(4-alkoxyphenyl)porphyrin aluminum(III)] were synthesized. Their molecular structures were characterized by UV-vis, 1H NMR, IR, MS spectra and elemental analysis, the results show that there two porphyrin molecules linked across Al—O—Al bond to form a dimer. Differential scanning calorimetry (DSC) and polarizing microscope (PM) were used to study their liquid properties. Among them, nine are found to exhibit liquid crystal (LC) properties, and most of them displayed as heating monotropic liquid crystals. There are one or two mesophases and certain phase transition temperature, ΔH and temperature range of liquid crystal (ΔT). The effects of alkoxy chains, metal ions of complexes and molecular space structure on liquid properties have been investigated. |
| Keywords: | porphyrinaluminum complex synthesis characterization liquid crystal property |
