1,3,5-Trifluoronaphthalene derivative of the 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>, in which B is (1) and R<1>(-A<1>-M<1>)a(-A<2>-M<2>) and (-M<3>-A<3>)(-M<4>-A<4>)R<2> mean mesogene radicals, are suited as components of liquid crystal in particular ferro-electric mixtures. |
