##STR1## Compounds of formula (I) where R is C.sub.1-15 alkyl, X is hydrogen, fluorine or chlorine, m and n are independently selected 1 or 0, W is C.sub.1-15 alkyl or alkoxy, CN or halogen, rings A and B are independently selected from phenyl, laterally fluoro- or chloro- substituted phenyl, transcyclohexyl, pyridyl, pyrimidyl or dioxanyl. Preferred embodiments have R=C.sub.3-8 and where W is alkyl or alkoxy then it is also preferable that W=C.sub.3-8. Where m=0, then preferably W=CN, and where m=1, then preferably W=alkyl.
化合物的公式为(I),其中R为C.sub.1-15烷基,X为氢、氟或氯,m和n分别独立选择1或0,W为C.sub.1-15烷基或烷氧基、CN或卤素,环A和环B分别独立选择自苯基、侧链氟或氯取代的苯基、顺式环己基、吡啶基、嘧啶基或二氧杂环基。优选实施例中,R=C.sub.3-8,当W为烷基或烷氧基时,优选W=C.sub.3-8。当m=0时,优选W=CN,当m=1时,优选W=烷基。
