Abstract:
A tetrahydronaphthalene derivative represented by a general formula (I) (wherein, R represents a saturated or unsaturated alkyl group or alkoxyl group of 1 to 20 carbon atoms which may incorporate a branched chain and may be substituted with 1 to 7 fluorine atoms or alkoxyl groups of 1 to 7 carbon atoms; linkage groups La, Lb, Lc and Ld each represent independently a single bond, â€”CH2CH2â€”, â€”CH&boxH;CHâ€”, â€”CH(CH3)CH2â€”, â€”CH2CH(CH3)â€”, â€”CH(CH3)CH(CH3)â€”, â€”CF2CF2â€”, â€”CF&boxH;CFâ€”, â€”CH2Oâ€”, â€”OCH2â€”, â€”OCH(CH3), â€”CH(CH3)Oâ€”, â€”Câ‰¡Câ€”, â€”CF2Oâ€”, â€”OCF2â€”, â€”COOâ€”, â€”OCOâ€”, â€”COSâ€” or â€”SCOâ€”; Z represents a fluorine atom, chlorine atom, cyano group, cyanato group, trifluoromethoxy group or a difluoromethoxy group; ring A, ring B and ring D each represent independently a trans-1,4-cyclohexylene group, a trans-decahydronaphthalene-2,6-diyl group, a trans-1,3-dioxane-2,4-diyl group, or a 1,4-phenylene group which may be substituted with one or two fluorine atoms, a pyridine-2,5-diyl group, a pyrimidine-2,5-diyl group, a pyrazine-2,5-diyl group, a pyridazine-3,6-diyl group, and a naphthalene-2,6-diyl group which may be substituted with one or two fluorine atoms; ring E represents independently a 1,4-phenylene group which may be substituted with one or two fluorine atoms, and a naphthalene-2,6-diyl group which may be substituted with one or two fluorine atoms, ring C represents either one of a general formula (IIa) and a general formula (IIb) (wherein, X1, X2, X3, X4, X5 and X6 each represent independently a hydrogen atom or a fluorine atom); and na, nb, nc and nd each represent independently either 0 or 1;although, in a case in which nc=1 and nd=0, ring D represents a 1,4-phenylene group which may be substituted with one or two fluorine atoms and/or a naphthalene-2,6-diyl group which may be substituted with one or two fluorine atoms; in a case in which Z is a cyano group, R is an unsubstituted and saturated alkyl group or alkoxyl group, na=nc=nd=0 and nb=1, or nb=nc=nd=0 and na=1, ring A and ring B are 1,4-phenylene groups, La and Lb are single bonds, and ring C is said general formula (IIa), then at least one of X1, X2 and X3 represents a fluorine atom; in a case in which Z is a cyano group, R is an unsubstituted and saturated alkyl group or alkoxyl group, na=nb=nc=0 and nd=1, or na=nb=nd=0 and nc=1, ring E and ring D are 1,4-phenylene groups, Lc and Ld are single bonds, â€”OCH2â€” or â€”COOâ€” linkages, and ring C is said general formula (IIa), then at least one of X1, X2 and X3 represents a fluorine atom; in a case in which Z is a cyano group, R is an unsubstituted and saturated alkyl group or alkoxyl group, na=nb=nc=0 and nd=1, or na=nb=nd=0 and nc=1, ring E and ring D are 1,4-phenylene groups, Lc and Ld are single bonds or â€”COOâ€” linkages, and ring C is said general formula (IIb), then at least one of X4, X5 and X6 represents a fluorine atom; in a case in which Z is a fluorine atom, R is an unsubstituted and saturated alkyl group or alkoxyl group, na=nb=nc=0 and nd=1, or na=nb=nd=0 and nc=1, ring E and ring D are 1,4-phenylene groups, Lc and Ld are â€”COOâ€” linkages, and ring C is said general formula (IIb), then at least one of X4, X5 and X6 represents a fluorine atom; and in a case in which ring C is said general formula (IIb), at least one of nc and nd is 1).
