Abstract

NEW MATERIAL:A liquid crystal compound expressed by formula I (R<1> is 6-12C alkyl; R<2> is straight-chain or branched 1-6C alkyl; n is 0 or 1). EXAMPLE:4-(4'-n-Octyloxybiphenyl-4-carbonyl)oxyphenyl-3-isopropyloxy-1 -methyl butyl ether. USE:Useful as a component of ferroelectric liquid crystal compositions, capable of exhibiting a high speed of response in image display and ferroelectricity within a wide temperature range and practically usable in high-density and large-sized displays, etc. PREPARATION:A diol expressed by formula II is used as a raw material and reacted with acetoxybenzoyl chloride to provide a product expressed by formula III, which is then alkoxylated with an alkyl iodide. Benzylamine is subsequently dripped into a solution of the obtained product in an alcohol and reacted therewith to afford a phenolic derivative expressed by formula V, which is subsequently condensed with an alkoxybiphenylcarboxylic acid in the presence of dicyclohexylcarbodiimide to provide the aimed compound expressed by formula I.
