Abstract:
A chiral swallow-tailed liquid crystals synthesized from chiral material comprised of alkyl(s)-2-{6-[4-(4'-alkyloxyphenyl)benzoyloxy]-2naphthyl}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, and having a formula ##STR4##in which R.sub.1 =--C.sub.m H.sub.2m+1, R.sub.2 =--(CH.sub.2)qCH(C.sub.n H.sub.2n+1).sub.2, m=6-20, q=0, 1 and n=1,2 or 3, A represents a rigid core, having a formula ##STR5##
