| 摘要 |
5,7-difluoro-1,2,3,4-tetrahydronaphthalene 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> in which B (i) is 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, which are suitable as constituents of specially ferroelectric liquid crystal mixtures.
