    摘要: The present invention provides liquid crystalline compounds having compatibility with the other liquid crystal materials and excellent stability, and having low viscosity and high transition temperature of the isotropic phase, liquid crystal compositions containing at least one kind of the liquid crystalline compounds, and liquid crystal display devices constituted by using the liquid crystal compositions. The liquid crystalline compounds are represented by the following formula:

            R-A 1 -Z 1 -A 2 -Z 2 -A 3 -Z 3 -A 4 -(CH 2 ) m -X     (1)

    wherein R indicates H or an alkyl group having 1 to 10 carbon atoms (one or more methylene group (-CH 2 -) in the alkyl group may be replaced by -O-, -S-, -CO-, -CH=CH- or -C≡C-, but -O- or -S- are not continuous), m indicates an integer of 1 to 10; X indicates F, Cl, Br, I or OH; A 1 , A 2 , A 3 and A 4 , each independently, indicate a trans-1,4-cyclohexylene group, a 1,4-phenylene group in which one or more hydrogen atoms on the ring may be substituted by a fluorine atom, a cyclohexenylenediyl group, a pyrimidine-2,5-diyl group, a pyridine-2,5-diyl group or a 1,3-dioxane-2,5-diyl group; Z 1 , Z 2 and Z 3 , each independently, indicate -(CH 2 ) 2 - or a covalent bond, and at least two of Z 1 , Z 2 and Z 3 indicate covalent bonds.

    摘要: A 2-(alkyl-cyclohexyl)-1-propanol is disclosed. The compound is represented by formula (I):
    wherein R₁ and R₂ individually represent a group selected from the members consisting of methyl-, ethyl-, n-propyl-, i-propyl-, t-butyl-, and sec-butyl groups, provided that the total carbon atoms of the R₁ and R₂ groups are 4 to 7;
    either R₁ and R₂ is a hydrogen atom, the other being a cyclohexyl group; or R₁ and R₂ together form a hexamethylene ring together with 2 carbon atoms in the cyclohexane ring. The compound possesses a long-lasting, woody, floral odor, and can be widely used as perfumery materials such as perfumes, soaps, shampoos, aromatic goods, and detergents.
