Title (EN) DISPIROTETRADECANE
(FR) DISPIROTETRADECANES
Abstract:
(EN) Dispirotetradecane of formula (I), in which R1 and R2 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 R1 and R2 also being H, F, Cl, Br, J, CN, NO2, NCS; A1 and A2 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, A1 and A2 can, if necessary, also be substituted laterally or axially by F, Cl, CN, CH3; Z1 and Z2 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; X1, X2, X3 and X4 are independently of one another H, F, Cl or CN; and one or both of the CX1X2 and CX3X4 groups may be C=0, can be used as components of liquid crystal phases.
(FR) Dispirotétradécanes de formule (I), dans laquelle R1 et R2 sont, indépendamment l'un de l'autre, un alkyle comprenant de 1 à 12 atomes de carbone, 1 ou plusieurs groupes CH2 non-adjacents pouvant également être remplacés par -O-, -CO-, -CO-O-, -O-CO-, -O-COO-, et/ou -CH=CH-(trans), l'un des résidus R1 et R2 étant également H, F, Cl, Br, J, CN, NO2, NCS; A1 et A2 sont, indépendamment l'un de l'autre, trans-1,4-cyclohexylène, un ou deux groupes CH2 non-adjacents pouvant être également remplacés par -O- et/ou -S- ou 1,4 phénylène, un ou plusieurs groupes pouvant également être remplacés par N, A1 et A2 peuvent, s'il y a lieu, être également substitués latéralement ou axialement par F, Cl, CN, CH3; Z1 et Z2 sont, indépendamment l'un de l'autre, -CO-O-, -O-CO-, -CH2CH2-, -CH2-O-, -OCH2- ou bien une liaison simple; m et n sont, selon le cas, 0, 1 ou 2; (M + n) est 0, 1 ou 2; X1, X2, X3 et X4 sont, indépendamment les uns des autres, H, F, Cl, ou CN; et un des groupes CX1X2 et CX3X4 ou les deux peuvent signifier C=O. Ces composés peuvent être utilisés comme constituants de phases crystallines liquides.
