A novel wing shaped achiral antiferroelectric liquid crystalline compound, 1,3-phenylene bis-[phenylene-1-biphenyldicarboxylato)-3-(4-n-tetradecyloxybenzoyl)biphenyl dicarboxylate] (abbreviated as PBPBTB), having 1,3-phenylene [4-biphonyldicarboxylate-(4-n-tetradecy-loxy benzoate)] units as wings, has been synthesized while its liquid crystalline behaviour is characterized by thermal microscopy (TM), differential scanning calorimetry (DSC), spontaneous polarization (P-s) and response times (tau) studies. The preliminary investigations on the ferroelectric properties of the present material show the presence of an antiferroelectric, phase.
