| Abstract: | Using methyl gallate as starting material, dodecyl gallic acid derivative 2 was obtained. Compound 2 was ammonlyzed by hydrazine hydrate to afford compound 3. Then reacting compound 3 with phenylenediamine, novel gallic acid Schiff base dimer was synthesized in simple separation and high yield of 80%. The structures of new compounds were characterized by 1H NMR spectra and MS spectra. The studies of DSC curves and POM showed it exhibited good property of liquid crystal. |
