Abstract
The trans isomer of the 2-(p-cyanophenyl)-5-alkyl-l,3-dithianes, synthesized by the acid-catalyzed thioacetalization of p-cyanobenzaldehyde and dithiols, were separated by means of centrifugal liquid chromatography and recrystallization. Several properties of a liquid crystal mixture containing 2-(p-cyanophenyl)-5-alkyl-1,3-dithianes were measured. The values thus obtained were compared with those for mixtures containing other p-cyanophenyl compounds. The principal feature of the mixture containing 2-(p-cyanophenyl)-5-alkyl-l,3-dithianeiss a low threshold voltage.Keywords
