(E)-1-Aryl-2-cyclohexyl-1,2-difluoroethylenes with optically active side chain were examined in purpose of application as chiral additive for STN liquid crystal devices. These compounds were derived from the optically active alcohols or carboxylic acids. Ether type compounds were synthesized from optically active alkoxyphenyllithium and 4-alkylcyclohexyltrifluoroethylene. Ester type compounds were obtained from the trifluoroethylene compound with p-bromophenyllithium or p-t-butyldimethylsilyloxyphenyllithium, respectively, followed by esterification.
