Abstract
An antiferroelectric liquid crystal material, (S)-4-(2-chloro-3-phenyl-1-(2-methylbutyloxy)carbomato- 4ʹ-n-dodecyloxy biphenylcarboxylate (CPCDBD), has been synthesized by using (S)-2-amino- 3-(4-hydroxy)phenyl propionic acid (L-tyrosine) as one the optically active ingredients. Preliminary investigations on this material reveal high spontaneous polarization (~ 145 nC/cm2) in the antiferroelectric Sm-CA* phase. Possible structural contributions towards the appearance of antiferroelectric ordering are discussed.
