| titleOfInvention | Cyclic hydrocarbon derivative and liquid crystal composition containing the same |
| abstract | A novel cyclic hydrocarbon derivative is disclosed, which is represented by formula (I):n n wherein Y¹ and Y² each independently represent a fluorine atom, a chlorine atom, a cyano group, a cyanato group (OCN), a thiocyanato group (SCN), a trifluoromethoxy group (OCF₃), a difluoromethoxy group (OCF₂H), a 2,2,2-trifluoroethoxy group (OCH₂CF₃), a trifluoromethyl group (CF₃), R, -OR, -COOR or -OCOR, wherein R represents an alkyl group having from 1 to 20 carbon atoms, an alkenyl group having from 2 to 20 carbon atoms or an alkoxylalkyl group having from 2 to 20 carbon atoms, provided that at least one of Y¹ and Y² represents R, -OR, -COOR or -OCOR; Z, Z¹, Z², Z³, and Z⁴ each independently represent a single bond, -CH₂CH₂-, -CH=CH-, -C≡C-, -COO-, -OCO-, -CH₂O-, -OCH₂-, -(CH₂)₄-, -(CH₂)₃-O- or -O-(CH₂)₃-; ring A represents a group of formula (II):n n wherein X¹, X², X³, X⁴, X⁵, X⁶, X⁷, X⁸, X⁹, and X¹⁰ each independently represent a hydrogen atom (H) or a deuterium atom (D), provided that at least one of them represents a deuterium atom (D); rings K, L, J, M and N each independently represent a trans-1,4-cyclohexylene group, a 1,4-cyclohexenylene group, a trans-1,4-cyclohexylene group substituted with 1 to 4 substituents selected from a fluorine atom and a cyano group, a 1,4-phenylene group, a 1,4-phenylene group substituted with 1 to 4 substituents selected from a fluorine atom, a chlorine atom, a cyano group and a methyl group, a 1,3-dioxane-2,6-diyl group, a pyrimidine-2,5-diyl group, a pyridine-2,5-diyl group, a pyrazine-2,5-diyl group or a group of formula (III):n n wherein X¹¹, X¹², X¹³, X¹⁴, X¹⁵, X¹⁶, X¹⁷, X¹⁸, X¹⁹, and X²⁰ each independently represent a hydrogen atom (H) or a deuterium atom (D), provided that at least one of them represents a deuterium atom (D); in which the ring of formula (III) may be the same or different with ring A; and k, l, m, and n each independently represent 0 or 1, provided that the sum of k, l, m, and n is 0, 1 or 2. The compound of the present invention is useful as an electro-optic liquid crystal display material. |
