| titleOfInvention | Optically active naphthalene derivatives |
| abstract | ABSTRACT OF THE DISCLOSURE The present invention is directed to optically active compounds each containing a naphthalene skeleton, and to liquid crystal compositions which contain the aforesaid optical active compounds, these compositions being suitable for ferroelectric liquid crystal devices having excellent photostability and chemical stability and having a rapid responsivity. The compounds of the present invention are represented by the general formula ............. (I) wherein X is a hydrogen atom, a halogen atom, a cyano group, an alkyl group or a methoxy group, latter two groups each having 1 or 2 carbon atoms; and A and B are independently represented by following formula and at least one of them contains an asymmetric carbon atom. wherein C and D rings are independent and each of them is a 1,4-phenylene, 2,6-naphthylene, pyrimidine-2,5-diyl, trans-1,4-cyclohexylene, trans-1,3-dioxane-2,5-diyl, trans-1,3-oxathian-2,5-diyl, trans-1,3-dithian-2, 5-diyl or 1,3,2-dioxaborinana-2,5-diyl group; each of m and n is an interger of 0, 1 or 2; each of Z1, Z2, Z3 and Z4 is a bonding group of one or more selected from the group consisting of a single bond, -C(O)-, -O-, -CH2-, -CH=N-, -CH=CH-, -C?C-, -N=N- and -N(O)=N-; and Y is a hydrogen atom, a halogen atom, a cyano group, a straight-chain or branched alkyl group or an alkenylalkyl group, latter two groups each having 1 to 20 carbon atoms. |
