New family of liquid crystalline compounds with high dipole moment of the general formula : [GRAPHICS] has been synthesised. On the basis of texture observation, DTA calorimetry and thermooptics, smectic A, Smectic E and nematic phases were identified. The temperatures and enthalpies of phase transition are discussed and compared with the analogous Schiff base family, 4-chlorobenzylidene-4’alkoxyanilines.
