Ferroelectric liquid crystal compounds with cyclohexenyl cores and compositions containing them

Ferroelectric liquid crystal compounds and compositions containing cyclohexenyl derivatives are provided. Specifically provided are compounds of formula: STR1 wherein R1 and R2 can be an alkyl, cycloalkyl, alkenyl, alkoxy, thioalkyl, alkylsilyl group having from one to about twenty carbon atoms. Y denotes --COO--, --OOC--, --CH2 O--, or --OCH2 --; and Ar1 and Ar2, independently of one another, can be selected from the group consisting of phenyl rings, halogenated phenyl rings and nitrogen-containing aromatic groups. In preferred embodiments the compounds of this invention contain at least one nitrogen-containing aromatic ring. Ar1 and Ar2 can be selected from 1,4-phenyl, mono- or dihalogenated 1,4-phenyl, 2,5-pyridinyl, 2,5-pyrimidyl, 2,5-pyrazinyl, 2,5-thiadiazole, 3,6-pyridazinyl and 1,4-cyclohexyl either or both be chiral racemic groups or chiral nonracemic groups.

SYNTHESIS OF ARYL 4-ALKYL-1-CYCLOHEXENE-1-CARBOXYLATES AND 4-ALKYL-3-CYCLOHEXENE-1-CARBOXYLATES AND THEIR MESOMORPHOUS CHARACTERISTICS

The reaction of 4-alkyl-1-cyclohexene-1-carbonyl and 4-alkyl-3-cyclohexene-1-carbonyl chlorides with 4-substituted phenols gave mesomorphous esters characterized by higher and lower formation temperatures, respectively, and a narrower temperature range for the existence of the nematic phase than the analogous derivatives of trans-4-alkylcyclohexane-1-carboxylic acids.
