Synthesis and characterization of new homologous series of unsymmetrical liquid crystalline compounds based on chalcones and 3, 5-disubstituted isoxazoles

Two homologous series of unsymmetrical alkylated chalcones and 3,5-diaryl isoxazoles, consisting of 20 members, with various n-alkyl bromides (n=2?7, 10, 12, 14, 16) have been synthesized and studied for their liquid crystalline property. Simple strategy was employed to achieve the target materials. Flexibility in the synthesized molecules is provided by attaching straight alkoxy chains, where one terminal group is fixed and other terminal group is varied. The synthesized compounds were characterized on the basis of Mass, IR and NMR spectroscopy. The stability and the range of the mesophases increased with the length of the chain on the isoxazoles. The melting point, transition temperatures and enantiotropic liquid crystal morphologies were determined by polarizing optical microscopy (POM) in conjunction with a hot stage and by differential scanning calorimetry (DSC).

Synthesis and liquid crystalline properties of a new homologous series of 4,5-disubstituted 2H-[1,2,3]-triazoles via azide-chalcone oxidative cycloaddition reaction

A new homologous series of 4,5-disubstituted 2H-[1,2,3]-triazole derivatives were synthesized from chalcones and sodium azide via oxidative cycloaddition reaction; CuI was used as catalyst. Flexibility in the synthesized molecules was provided by attaching straight alkoxy chains. The synthesized compounds were characterized by elemental analysis, and 1HNMRand 13CNMRand LC-MS spectroscopies . The stability and range of the mesophases increased with the length of the chain on the triazoles. The melting point, transition temperatures, and enantiotropic liquid crystal morphologies were determined by differential scanning calorimetry (DSC) and polarizing optical microscopy (POM) equipped with a hot stage.
