Paragraph 0093, (2018/10/16)
PROBLEM TO BE SOLVED: To provide a novel liquid crystalline compound that is low in dielectric anisotropy, has responsiveness, and changes its birefringence by application of voltage. SOLUTION: The present invention provides a compound represented by formula (1) (In the formula (1), R1, R2 and R3 independently represent a hydrogen atom or C1-C10 alkyl, in the alkyl, at least one -CH2- may be substituted by -O-, -S-, -CO-, or -SiH2-, and at least one -(CH2)2- may be substituted by -CH=CH-or -C≡C-. n is an integer of 0-4. m is an integer of 1 or 2. Z1 and Z2 are -CH=CH-). SELECTED DRAWING: None COPYRIGHT: (C)2016,JPOandINPIT

Various laterally fluoro-substituted benzonitriles have been prepared containing a trans-4-(n-alkyl)cyclohexane ring linked to the 4-position of the benzonitriles either through a methyleneoxy (-CH2O-) or an ethylene (-CH2CH2-) bridge.The bridging group links the benzonitrile and cyclohexane rings either directly or through an additional 1,4-bonded cyclohexane or benzene ring.The synthesis and liquid-crystal transition temperatures of these new compounds are described.In several cases the nematic-isotropic transition temperatures of F-substituted benzonitriles are found to be higher than those of the non-laterally substituted analogues.

Pyrimidine derivatives of the formula STR1 wherein at least one of rings A and B is a trans-1,4-disubstituted cyclohexane ring and the other, optionally, may be aromatic and R is straight-chain alkyl or alkoxy of 1 to 10 carbon atoms or a branched-chain alkyl group of the formulas C2 H5 --CH(CH3)--(CH2)n --wherein n is 1, 2 or 3, are described. Processes for the preparation of the compounds of formula I as well as their uses in liquid crystalline mixtures are also described.
