摘要： Liquid crystal mixtures comprising at least one of the compounds of formula (I) containing a heterocyclic five-membered ring and with a carbon-carbon double bond in the termninal group are new. RJ=CnH2n+1CH=CHCmH2mZ1; n=1-5; m=0-5; and q=0, 1 or 2; A1 and A2=2,5-disubstituted furan, 2,5-disubstituted thiophene, 2,5-disubstituted oxazole, 2,5-disubstituted thiazole, 2,5-disubstituted 1,3,4-oxadiazole, 2,5-disubstituted 1,3,4-thiadiazole, 1,4-disubstituted benzene, 2,5-disubstituted pyrimidine, 2,5-disubstituted pyridine, 2,6-disubstituted naphthalene; laterally substituted 1,4-disubstituted benzene, laterally substituted 2,5-disubstituted pyrimidine, laterally substituted 2,5-disubstituted pyridine or laterally substituted 2,6-disubstituted naphthalene (lateral substituents=F, Cl, Br or CN); A3=any A1 or 1,4-disubstituted bicyclo(2.2.2)octane, trans-1,4-disubstituted cyclohexane, trans-2,5-disubstituted dioxane or 1,4-disubstituted piperidine; Z1=O, COO or OOC; Z2 and Z3=direct bond, COO, OOC, C2H4, CH2O, OCH2, C4H8, C3H6O, (E)-CH═CHC2H4, (Z)-CH2CH═CHCH2, (E)-CH═CHCH2O or —C equivalent to C—; R=1-20C alkyl, alkoxy, alkenyl, alkenyloxy, alkanoyloxy, alkenoyloxy or OCpF2p+1; and p=1-20. When Z1=O and m=1, 3 or 5 the carbon-carbon double bond configuration in RJ is E. When Z1=O and m=2 or 4 the carbon-carbon double bond configuration in RJ is Z. When Z1=COO or OOC and m=0, 2 or 4 the carbon-carbon double bond configuration in RJ is E. When Z1=COO or OOC and m=1, 3 or 5 the carbon-carbon double bond configuration in RJ is Z.
