Synthesis of liquid-crystalline 4,4′-dodecyloxybenzoyloxybenzoyl-4-oxy-2-hydroxybenzaldehyde and related azomethine

4,4′-Dodecyloxybenzoyloxybenzoyl-4-hydroxy-2-hydroxybenzaldehyde and the related linear azomethine, the intermediates at the formation of iron(III)-containing complexes, were synthesized. These compounds were characterized by thin layer chromatography, elemental analysis, IR, NMR spectroscopy, mass spectrometry, and by the data of differential scanning calorimetry. The aldehyde and the azomethine show mesomorphic properties.
