    • Dispirotetradecane of formula (I), in which R and R are, independently of one another, alkyl with 1 to 12 C atoms, wherein also one or several non-adjacent CH2 groups may be replaced by -O-, -CO-, -CO-O-, -O-CO-, -O-COO-, and/or -CH=CH-(trans), one of the residues R and R also being H, F, Cl, Br, J, CN, NO2, NCS; A and A are, independently of one another, trans-1,4-cyclohexylene, wherein also one or two non-adjacent CH2 groups may be replaced by -O- and/or -S- or 1,4 phenylene, wherein also one or several groups can be replaced by N, A and A can, if necessary, also be substituted laterally or axially by F, Cl, CN, CH3; Z and Z are, independently of one another, -CO-O-, -O-CO-, -CH2CH2-, -CH2O-, -OCH2- or a single bond; m and n are as applicable 0, 1 or 2; (m + n) is 0,1 or 2; X , X , X and X are independently of one another H, F, Cl or CN; and one or both of the CX X and CX X groups may be C=0, can be used as components of liquid crystal phases.
