STR1 Novel cyanohydrin derivatives of general formula (I) wherein R1 is hydrogen, alkyl, alkoxy, perfluoroalkyl or perfluoroalkoxy, R2 is alkyl, r is 1 to 10, n and m are 0 or 1, provided if both n and m are 0 then X is (II) or (III), where (F) indicates one or more optional fluorines, p is 0 or 1, Z is a single bond if p is 0 and COO is p is 1; and if one or both of n or m are 1 then X is (IV), where each ring A, B and C is phenyl, fluoro- or chloro-phenyl, cyclohexyl, pyrimidyl, pyridyl, or dioxanyl, A, B and C are single bonds or linking groups, and (a+b+c) is 2 or 3. Liquid crystal materials containing these compounds are also described.
Cyano-alicyclic esters in liquid crystal compositions
-
, (2008/06/13)
Compounds suitable for use as constituents of ferroelectric smectic liquid crystal compositions, which are ester of formula (I), where R2 and R3 together represent the residue of an alicyclic hydrocarbon ring system where *C is an asymmetric carbon atom and X is a chain of up to three linked aromatic or alicyclic six-membered organic cyclic groups, laterally and/or terminally substituted. Preferred compounds have a formula (II), where R1 is alkyl or alkoxy, A, B, and D are phenyl, fluoro or chloro substituted phenyl or cyclohexyl, n is 0 or 1, Y is a bond or CH2 CH2 if n is 0, or a bond CH2 CH2 COO or COO if n is 1. Preferred groups C(CN)R2 R3 are formula (III) and (IV). STR1
