Abstract
New liquid crystal compounds: (+)-4'-Alkoxyphenyl 4-[5-(2-methylbutyl)-1,3-dioxan-2-yl]benzoates (5) were synthesized. The mesomorphic behavior of these compounds is compared with those of (+)-4-(2-methylbutoxy)phenyl 4-(5-alkyl-1,3-dioxan-2-yl)benzoates (6) and (+)-4-(5-alkyl-1,3-dioxan-2-yl)-phenyl 4-(2-methylbutoxy)benzoates (7). The four Compounds (5) exhibit only the cholesteric phase and their transition temperatures to the isotropic state are lower than those of corresponding compounds (6) and (7). These properties may originate in the greater molecular width caused by 2-methylbutyl group at the 5 position of the 1,3-dioxane ring
