Abstract
Rod-shaped thiocyanic compounds based on a 4-benzoyloxy-biphenyl mesogen were prepared by nucleophilic substitution with a thiocyanic salt.The number of carbon atoms in one terminal alkyloxy chain was 6,8 and 10.The mesomorphic properties of the synthesized compounds were characterized by means of polarized optical microscopy and differential scanning calorimeter.The results demonstrated that the thiocyanic compounds exhibited thermotropic smectic A and nematic phases.The isotropic point of the liquid crystals decreased with the increase in length of the terminal alkyloxy chain.
