Preparation and study of new phenolic azomethine compounds

New phenolic azomethine compounds having the general formula HO-M-X were prepared by the classical condensation reaction of aromatic amines with various para-substituted benzaldehydes. M represents a calamitic azomethine mesogen and X is -NO2; -N(CH3)2; -N(CH2CH 3)2 or -NH2. The thermal properties of these compounds were investigated using different techniques, such as differential scanning calorimetry (DSC), thermo-optical analysis (TOA), polarized light microscopy (PLM) and thermogravimetric analysis (TGA). The phenolic azomethines having aspect ratio (L/D) values greater than 3.7 exhibited thermotropic liquid crystalline (TLC) behavior. These compounds showed absorption bands in UV due to both the π - π* and π - π* electronic transitions which seemed to be influenced by the electrono-donor or electrono-acceptor character of the end groups, Some structural parameters, such as molecular polarizability (a), stress optical coefficient (SOC) and anisotropy of polarizability (b 1-b2), were calculated and proved to correlate with both the UV and TLC behavior of these phenolic azomethine compounds.
