Abstract
(+)-4-(2-Methylbutoxycarbonyl)phenyl 4-(5-alkyl-1,3-dioxan-2-yl)benzoate (12), (+)-4-(2-methylbutoxy)-phenyl 4-(5-alkyl-1,3-dioxan-2-yl)benzoate (11) and the corresponding 1,3-oxathiane (13, 14) and 1,3-dithiane compounds (15, 16) were synthesized. The mesomorphic behaviors of these compounds were measured. Compounds 12 exhibited the ferroelectric liquid-crystal behavior (R=n-C11H23: −4 SmC* 94 °C), while the corresponding 1,3-oxathiane (13, 14) and 1,3-dithiane compounds (15, 16) did not exhibit such behavior. Therefore, 1,3-dioxane compounds are more favorable for transition of SmA to SmC* than the 1,3-oxathiane or 1,3-dithiane analogs.Keywords
