摘要： A liquid crystalline alkenyltolan derivative expressed by the general formula CtH2t−1—G—(CH2)m—A1—B1—(A2—B2)n—(A3—B3)p—A4—X wherein A1, A2, A3, and A4 independently represent a 1,4-cyclohexylene, 1,4-phenylene in which one or two hydrogen atoms may be replaced by a fluorine atom(s), dioxane-2,5-diyl, or pyrimidine-2,5-diyl group; B1, B2, and B3 independently represent a covalent bond, an 1,2-ethylene, 1,2-ethenylene, 1,2-ethynylene, oxymethylene, methylenoxy, carbonyloxy, or 1,4-butylene group provided that at least one of B1, B2, and B3 represents an 1,2-ethynylene group; G represents a covalent bond or an oxygen atom; CtH2t−1 represents an alkenyl group having t carbon atoms; n and p are each 0 or 1; and X represents an alkyl group having 1 to 10 carbon atoms. The derivative provides a liquid-crystal compound and a liquid-crystal composition which have high anisotropy, high elastic constant ratio, excellent comparability with other liquid-crystal compounds, and low viscosity and are chemically and physically stable.
