Synthesis of Liquid Crsytal Compoun With Azo Linakhe and Effect of Terminal Group on Liquid Crystal Properties

ABSTRACT

          The polar ester terminal group have an impact on the mesomorphic characteristics of the synthesized new LC. The 12 compounds in the current series, D-1 through D-16, are distinguished by their methylene groups. Out of the twelve compounds, five are nematic and seven are smectic. The mesophase behaviour was carried out by polarized optical microscope (POM).  The structure of LC compound was confirm by ¹H-NMR, IR and Mass spectroscopy. The smectic thermal stability is 131.14 ⁰C and nematic thermal stability is 181.40 ⁰C. The mesophase length is 12.5 ⁰C to 80.8 ⁰C.
