摘要：

The synthesis and mesomorphic properties of some new Schiff bases based on a 4-methyl-1,3-diaminobenzene core are reported. The compounds were prepared by condensation reaction of the central core with azobenzene containing mesogenic units [(4-(4-alkoxyphenylazo)-benzaldehydes or 4-(4-alkanoyloxyphenylazo)-benzaldehydes]. The majority of the new bent-shaped Schiff bases presented enantiotropic liquid crystalline properties evidenced by DSC and POM analysis. All the synthesized compounds presented a very good thermal stability as evidenced by thermogravimetric analysis.
