  Synthesis and mesomorphic properties of new chalconyl-ester based liquid crystals: The effect of tail group

  摘要：

  A new homologous series viz. 4-(3-(3, 4-dioctadecyloxy) phenyl)-3-oxoprop-1-en-1-yl) phenyl-3-(4-n-alkoxy phenyl) cinnamate) based on two linking groups have been synthesized and characterized. The mesomorphic properties of these compounds were observed by optical polarized light microscopy (POM) and confirmed by differential scanning calorimetry (DSC). All synthesized compounds exhibited LC behaviour except compound C-1. Thermal stability of smectic and nematic phase of present series are 79.0 degrees C and 120.0 degrees C whose temperature range is vary from 14 to 20 degrees C and 24 to 56 degrees C respectively. The mesomorphic properties of present series were compared with other structurally related mesogenic homologous series to evaluate the effects of tail group on mesomorphism.

• Nitrochalcones as organogelators: evidence of the involvement of nitro groups and solvent in gel formation

  日期：——

  4-alkoxynitrochalcones have been synthesized and shown to be organogelators; dodecyloxy/benzyl alcohol gels have been studied by freeze-fracture electron microscopy, DSC and FTIR. We show that the nitro group is involved in the formation of the gel and that the gelator co-assembles with solvent molecules.

  In present study, we have synthesized such newly chalcone-ester linking group based homologous series containing disubstituted octadecyloxy tail part. A series of new chalcones with having three aromatic rings is synthesized and characterised by elemental analyses and spectroscopic techniques such as Fourier transform infrared [FT-IR] and proton magnetic resonance magnetic resonance [H-1 NMR] spectroscopy. The mesomorphic properties of these compounds were observed by optical polarized light microscopy (POM) and confirmed by differential scanning calorimetry (DSC). It is found that all the prepared materials display enantiotropic LCs phases except first three homologue in present series. Comp. C-1 to C-12 exhibits only enantiotropic nematic phase. However, in higher member comp.C-14 to C-18 shows enantiotropic SmC and nematic phase. Thermal stability of smectic and nematic phase of present series is found to be 51.33 degrees C and 109.0 degrees C.[GRAPHICS]
