An azo ester-based biphenyl substituted rod-shaped azo-based material has been synthesized and well-characterized and further studied their mesogenic, optical, and thermal properties. All the synthesized derivatives displayed enantiotropical nematic and SmC phases with good temperature range of mesophase which is further influence by the variation of alkyl chain. The present synthesized derivatives having left terminally substituted phenyl ring by -OR inbuilt with ester azo group and right terminally dodecyloxy tail (-OC12H25) at the right terminal end. The mesomorphism is measured by using POM, DSC, and high-temperature XRD technique, and the photophysical behavior was measured by UV-Vis spectroscopy.

The mesomorphic properties of linear shaped homologous series based on two linkage group have been designed and synthesized with different side chain substituents (-OR) on the one end of terminal side with presence of lateral nitro group and second terminal iodo substituted group. Novel series consists thirteen members (C1 to C8, C10, C12, C14, C16, C18). Compounds (C1 to C6) showed nonliquid crystalline properties while compound (C7 to C18) displayed smectic and nematogenic mesophase properties. The textures of smectic C and nematic phase are fan, schlieren and droplets type. All these compounds were characterized by spectroscopic techniques such as [FTIR] and 1H Nuclear magnetic resonance [NMR] spectroscopy. The mesomorphic properties of these compounds were observed by POM and further confirmed by DSC and XRD. Chalconyl ester based compounds (C3 to C12) shows good antibacterial as well as antifungal activity compared with corresponding standard drugs.
