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 is closely related to the nature of the substituent X present in N1 position of the heterocycle. (C) 2012 Elsevier B.V. All rights reserved.
