发明名称 DISUBSTITUTED PHENANTHRENE AND THEIR USE IN LIQUID CRYSTAL MIXTURE
摘要 PROBLEM TO BE SOLVED: To provide a new component for using in nematic liquid crystal or cholesteric liquid crystal mixture having a preferable viscosity/clear point ratio and a positive dielectric anisotropy. SOLUTION: This compound is expressed by formula (I). R1-A-Z1 (I). In the formula: R1 is a 1-8C alkyl or 2-8C alkenyl, in the each case one of (non terminal) -CH2- groups may be substituted with -O- or-C(=O)O-, and/or one or two or more H may be substituted with F, A is phenanthrene-2,7-diyl or 9,10- dihydrophenanthrene-2,7-diyl, Z1 is F, OCHxF3-x or CHxF3-x in each case x is 0, 1 or 2, and OC2HzF5-z or C2HzF5-z in each case z is 0, 1, 2, 3 or 4, CH=CF2 or Cl excluding 2-fluoro-7-methoxy-phenanthrene.
