    摘要： Novel chiral swallow-tailed liquid crystals synthesized from chiral material comprised of alkyl(s)-2-{6-[4-(4′-alkyloxyphenyl)benzoyloxy]-2-naphthyl}propionates having a rigid core, a chiral center directly linked to the rigid core, a chiral tail, and a swallow-tailed group linked to the chiral tail. The chiral center and the swallow-tailed group are arranged at the same side in the molecular structure of the chiral material. These structural characteristics enable the chiral material to have same property of threadholdless antiferroelectricity, and the advantage of simple manufacturing process. The chiral material shows an optimum application effect in liquid crystal displays.
