Synthesis of Mesogenic Compounds and Study the Effect of Terminal groups on their Mesomorphic Properties

Two long serieses containing azomethine , esters groups and three aromatic rings with CH3 and COCH3 on one side of series I and II respectively and thio alkyl group on the other side of both series, have been synthesized and identified by IR , 1H-NMR and elemental analysis. The mesomorphic properties of these compounds were investigated via differential scanning calorimetry and polarizing optical microscopy, and are discussed the effect of length of the thio alkyl and the type of the terminal groups on the mesomorphic properties
