HOE 91/F 352 Abstract of the disclosure Novel compounds fox use in liquid-crystal mixtures Compounds of the formula (I) R1-(A1)a(-M1)b-(-A2)c(-M2)d(-A3)e(-M3)f(-A4)g-H (I) in which the symbols and indices have the following meanings: R1 is H or a straight-chain or branched alkyl radical having 1 to 22 carbon atoms (with or without an asymmetrical carbon atom) in which, in addition, it is possible for one or two non-adjacent -CH2- groups to be replaced by -O-, -S-, -CO-, -CO-O-, -O-CO-, -CO-S-, -S-CO-, -O-CO-O-, -CH=CH-, -C=C-, .DELTA. or -Si(CH3)2-, and in which, in addition, one or more hydrogen atoms of the alkyl radical may be substituted by F, Cl, Br or CN, or is a chiral group, for example an epoxide, a dioxolane or a cyclic lactone, (A1)a(-M1)b-(-A2)c(-M2)d(-A3)e(-M3)f(-A4)g- is a system comprising 1 to 4 rings (cyclohexane, aromatic or heterocyclic), it being possible for the system to be linked in different ways. The compounds according to the invention increase the response speed of liquid crystal mixtures.
