New Chiral Liquid-Crystal Compounds - (S)-(+)-4-(4-(Methyl)-1,3-Dioxolan-2-Yl)-Phenyl-4-N-Alkoxybenzoates and 4-N-Alkoxycinnamates
New liquid crystal compounds, (S)-(+)-[4-(methyl)-1,3-dioxolan-2-yl]phenyl-4-n-alkoxybenzoates, I, and (S)-(+)-[4-(methyl)-1,3-dioxoian-2-yl]phenyl-4-n-alkoxycinnamates, II, have been synthesized and the thermotropic liquid-crystalline behaviour investigated. The compounds did not exhibit a chiral smectic C phase. The mesophases present in these compounds are cholesteric and smectic A phases. The transition temperatures of series II are higher than those for series I.
