A series of five-membered heterocyclic 1, 2, 3-triazole derivatives with different substituents in N1 position was synthesized. The heterocyclic moiety was connected through an ester function to a p-decyloxyphenyl or p-decyloxybiphenyl tails Polarized microscopy studies, X- ray scattering and differential scanning calorimetry (DSC) analysis revealed that the target compounds exhibit enantiotropic liquid crystalline properties. Their mesomorphic behavior ...
