摘要:
1. Claims for the Contracting States BE, CH, DE, FR, GB, IT, LI, NL, SE Compounds of the general formula see diagramm : EP0169327,P26,F1 wherein X represents a single covalent bond, the ethylene group -CH2 CH2 -, 1,4-phenylene, a 2,5-disubstituted pyrimidine ring or the group of the formula see diagramm : EP0169327,P26,F2 ring A represents trans-1,4-cyclohexylene or, when X represents a single covalent bond, also 1,4-phenylene, a 2,5-disubstituted pyrimidine ring or a trans-2,5-disubstituted m-dioxane ring ; and R1 signifies straight-chain trans-1-alkenyl with 2 to 12 carbon atoms or straight-chain trans-3-alkenyl with 4 to 12 carbon atoms or, when X represents -CH2 CH2 -, 1,4-phenylene, a 2,5-disubstituted pyrimidine ring or a group of formula IA or ring A denotes a 2,5-disubstituted pyrimidine ring or a trans-2,5-disubstituted m-dioxane ring, R**1 also signifies straight-chain alkyl with 1 to 12 carbon atoms ; and one of the benzene rings optionally has a lateral fluorine substituent. 1. Claims for the Contracting State AT A liquid crystalline mixture with at least 2 components, characterized in that at least one component is a compound of the general formula see diagramm : EP0169327,P27,F2 wherein X represents a single covalent bond, the ethylene group -CH2 CH2 -, 1,4-phenylene, a 2,5-disubstituted pyrimidine ring or the group of the formula see diagramm : EP0169327,P27,F3 ring A represents trans-1,4-cyclohexylene or, when X represents a single covalent bond, also 1,4-phenylene, a 2,5-disubstituted pyrimidine ring or a trans-2,5-disubstituted m-dioxane ring : and R**1 signifies straight-chain trans-1-alkenyl with 2 to 12 carbon atoms or straight-chain trans-3-alkenyl with 4 to 12 carbon atoms or, when X represents -CH2 CH2 -, 1,4-phenylene, a 2,5-disubstituted pyrimidine ring or a group of formula IA or ring A denotes a 2,5-disubstituted pyrimidine ring or a trans-2,5-disubstituted m-dioxane ring, R**1 also signifies straight-chain alkyl with 1 to 12 carbon atoms ; and one of the benzene rings optionally has a lateral fluorine substituent.
