PURPOSE: To obtain a new difluorocyclohexane compound useful as a component of liquid crystal material capable of realizing high-speed response.
CONSTITUTION: A compound (e.g. 4-(trans-4-nonyl-3,3-difluorocyclohexyl)-1- octyloxybenzene) expressed by formula I [A and B are 1,4-phenylene or naphthalene-s,6-diyl which may have 1-2 substituent groups (halogen or CN) and 1-2 CH in these groups may be replaced by N and further A is 1,4- cyclohexylene; Y is single bond, CH2CH2, CH2O, OCH2, COO, OCO, C≡C, etc.; 1-20C straight-chain or branched alkyl (one or two or more CH2, which is not adjacent, existing in group of R1 may be replaced by O or S) capable of having one or more F a substituent groups. The compound having m ring 1 can be produced from a compound expressed by the formula R1-B through compounds expressed by formula II to formula IV.
