Abstract
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-biphenyldicarboxylate-(4-n-tetradecyloxy benzoate)] units as wings, has been synthesized while its liquid crystalline behaviour is characterized by thermal microscopy (TM), differential scanning calorimetry (DSC), spontaneous polarization (Ps) and response times (τ) studies. The preliminary investigations on the ferroelectric properties of the present material show the presence of an antiferroelectric phase.
