| titleOfInvention | CHIRAL OR ACHIRAL CYCLIC COMPOUNDS. |
| abstract | Chiral or achiral cyclic compounds of formula (I): R1- (A1-Z1) m-A2-Q1-C * R ° X-Q2 (A3-Z2) n- (A4) o-R2, in which R1 and R2 , independently of one another, represent an alkyl or perfluoroalkyl group with 1 to 12 C atoms, in which also one or two non-contiguous CH2 or CF2 groups can be replaced by O atoms and / or groups -CO- and / or groups -CO-O- and / or groups -CH = CH- and / or groups -CHhalogen- and / or -CHCN- and / or groups -O-CO-CHhalogen- and / or -CO-O-CHCN-; one of the groups R1 and R2 also represents H, F, Cl, Br or CN, R1 is also -Q1-C * R ° X-Q2-R2, Q1, R °, X, Q2 and R2 having the notations indicated; A1, A2, A3 and A4, independently of one another, represent a 1,4-phenylene unsubstituted or substituted by one or two atoms of F and / or Cl and / or CH3 groups and / or CN groups, in which also one or two CH groups can be replaced by N; 1,4-cyclohexylene in which also one or two non-contiguous CH2 groups can be replaced by O atoms and / or S atoms; piperidine-1,4-diyl, 1,4-bicyclo (2,2,2) octylene-, 1,3,4-Thiadiazol-2,5-diyl, Naphtaline-2,6-diyl-, décahydronaphtaline-2, 6-diyl- or 1,2,3,4-tetrahydronaphthalin-2,6-diyl-; Z1 and Z2 each represent -CO-O-, -O-CO-, -CH2CH2-, -OCH2-, -CH2O-, -C = C- or a single bond; X is halogen, CN or CH3; R ° is an alkyl group with 1 to 10 atoms of C, different from X (and in the case where n = o = O, also of R2); C * is a crosslinked carbon atom with four different substituents; m and n, independently of one another, are 0, 1, 2 or 3; o is 0 or 1; (m + n + o) are 1, 2, 3 or 4, and Q1 and Q2, independently of each other, represent an alkylene with 1 to 4 C atoms, in which also a CH2 group can be replaced by -O-, -S-, -CO-, -O-CO, -CO-O-, -S-CO-, -CO-S-, -CH = CH-COO-, -CH = CH-, -CHhalogen- and / or -CHCN-; or even a simple bond. These compounds can be used as constituents of tilting smectic liquid crystal phases |
