New halogenated benzene derivatives of formula (I), where n is 1 to 7, the rings A and B each stand for trans-1,4-cyclohexylene, or one of the rings A and B also stands for 1,4-phenylene or 3-fluor-1,4-phenylene, X F, Cl, -CHF2, -CF3, -CN, -OCF3 or -OCHF2, Y and Z each independently stand for H or F, r = 1 or, if s = 1, B = trans-1,4-cyclohexylene and simultaneously X = -CHF2, -CF3, -OCF3 or -OCHF2 and r = 0, and s = 1 or, if B = 1,4-phenylene or 3-fluor-1,4-phenylene, s = 0. |
