| abstract | New liquid crystalline compounds containing the bicyclo[2,2,2]octane ring and the phenylisothiocyanato group in their molecules of the general formula 1:n wherein: R is a normal or branched alkyl H 2n+1 C n - or alkenyl H 2n-1 C n - group containing up to 15 carbon atoms, some of the hydrogen atoms in the alkyl chain being sometimes substituted by a fluorine atom, Z is a single bond or -COO-, -OOC-, -CH₂O- or -C≡C- group, the ring A is a 1,4-disubstituted benzene ring or 2,5-disubstituted pyrimidine ring or a 2,5-disubstituted pyridine ring or a 2,5-disubstituted 1,3-dioxane ring, m stands an integer 0 or 1, X1, X2 and X3 are identical or different and each of them denotes a hydrogen atom or a fluorine atom or a chlorine atom or a bromine atom or a cyano group, however, if m=1 and the ring A is not a benzene ring then Z is also a -CH₂CO-, -CO-CH₂-, -CH=CH-, CHYCH₂-, -CH₂-CHY-, -C₆H₄-CH₂-CHY-, -C₆H₄-CHY-CH₂-, or C₆H₄-C≡C- group where Y is a hydrogen atom or a fluorine atom or a chlorine atom or a cyano group or a methoxy group or a hydroxy group are prepared and used as component of liquid crystal mixture. Method manufacturing of compounds 1, the liquid crystal mixture containing compounds 1 and their use for electrooptical devices are described. |
