Synthesis and characterization of AZO-Benzothiazole compounds and study the effect of lateral substituents on their liquid crystalline properties supported by the theoretical results

Abstract

Compounds EB-4Cl and EB- 3,4Cl were prepared and diagnosed by spectral methods FTIR, NMR and Mass. They also studied by polarized microscope and did not diagnose any liquid crystalline phases in the compounds. The total dipole moment of the molecules and the length and width of the molecules as well as the length of the bonds were theoretically calculated.
