Synthesis, Characterization And Liquid Crystalline Properties Of (E)-4-((4- (Alkanoylthio)Phenyl)Diazenyl) Benzoic Acid

Abstract

In this study, a series of azo thioester consisting of 9 compounds were synthesized by using (E)-4-((4- mercaptophenyl)diazenyl)benzoic acid as backbone of compounds. These compounds were synthesized by diazotization of 4 -aminobenzoic acid then coupling with thiophenol, followed by acylation of thiol group with acid chloride (2-10 carbon atoms) in pyridine as a solvent. Synthesized compounds were characterized by using IR, 1H NMR spectroscopy, their melting p oints were determined, investigation of liquid crystalline properties indicated that no liquid crystal properties for these compounds.
