摘要: New bicyclohexylethanes of formula IR1--Cy--Cy--CH2CH2--A--(Cy)n--R2 (I)wherein R1 is alkyl; R2 is alkyl, in which one or two non-adjacent CH.sub.2 groups can be replaced by 0 atoms, or is F, Cl, Br, CN, --COOalkyl or --O--CO--alkyl; or one of the radicals R.sup.1 and R.sup.2 can also be H; A is Cy, or 1,4-phenylene which is unsubstituted or substituted by one or two F and/or Cl atoms and/or CH.sub.3 groups or by a CN group; Cy is 1,4-cyclohexylene and n is 0 or 1; the alkyl groups in each case containing 1-10 C atoms, with the proviso that n is 1 if A is Cy and R2 is CN, can be used as constituents of dielectrics for electrooptical display elements.
