Partially fluorinated compounds of formula (I): R<1>-A<1>-Z<1>-(A<2>-Z<2>)m-A<3>-(Y)n-Q-R<2> where R<1>, R<2>, A<1>, A<2>, A<3>, Z<1>, Z<2>, Y, m and n have the meanings given in claim 1 and Q stands for (CFH)o-CF<2>-CFH)p and, if n = 0, for -CF2-CF2-,-CH2CF2- or -CH2-CHF-, and o and p are each equal to 0 or 1, can be used as constituents of liquid crystalline media. |
