Bent-shaped mesogens possessing a biphenyl as a central core have been synthesized and the role of the terminal chain and the orientation of the ester as a linkage group have been investigated. For the studied molecular core we have established that both
New Liquid Crystal Compounds: (+)-4-Alkoxycarbonylphenyl-4-benzoate

New Liquid Crystal Compounds: (+)-4-Alkoxycarbonylphenyl-4-benzoates (5) were synthesized.The mesomorphic behavior of these compounds is compared with that of (+)-4-(2-methylbutyloxycarbonyl)phenyl 4-(5-alkyl-1,3-dioxan-2-yl)benzoates (6).Compounds 5 exhibited cholesteric and smectic A phases and their transition temperatures to the isotropic state were lower than those of corresponding compounds 6.These properties are supposed to originate in the greater molecular widths of the formers caused by 2-methylbutyl group at the 5 position of the 1,3-dioxane ring.Though compounds 6 exhibit the ferroelectric behavior, compounds 5 don't.This might mean that a short distance between the carbonyl and chiral group is one factor for the appearance of the SmC* phase.
