| abstract |
The invention relates to fluorinated naphthalene derivatives of formula (I) R<1>(-A<1>-M<1>)a(-A<2>-M<2>)b-B(-M<3>-A<3>)c(-M<4>-A<4>)d-R<2>, wherein B is (II) having the meaning (III), (IV) or (V) or is (VI) and R<1>(-A<1>-M<1>)a(-A<2>-M<2>) and (-M<3>-A<3>)(-M<4>-A<4>)R<2> stand for mesogene radicals. Said derivatives can be used as constituents for liquid crystal mixtures, more particularly for ferroelectric liquid crystal mixtures. |
