Abstract
NEW MATERIAL:A 4"-halogenophenyl ester of carboxylic acid having S-(+)-4- (2'-methylbutylphenyl) group of the formula (n, m are 0, 1; X is F, Cl; * is asymmetric carbon).
EXAMPLE: S-(+)-4-(2"-methylbutyl)biphenyl-4'-carboxylic-4"fluorobiphenyl etster.
USE: Liquid crystal for display elements: it has a spiral structure and is added to nematic liquid crystal for cholesteric-nematic phase transition mode displays or White-Taylor mode display elements or added to a nematic liquid crystal composition for TN-mode display element to improve its performance by reducing the formation of zebra pattern on the display surface.
PREPARATION: For example, S-(+)-4-(2"-methylbutyl)binphenyl-4-carboxylic acid is converted to its acid chloride, which is made to react with 4-halogenophenol in the presence of pyridine to give the compound of the formula.
