Abstract
NEW MATERIAL:A compound shown by formula I [R is 2-10C alkyl; 2MB is (S)-2-methylbutyl; x is 0-5; y is 0 or 1; m and n are 0 or 1; rings containing X and Y are groups shown by formula II - formula IV; C* is asymmetric carbon atom having absolute configuration of (R) or (S)]. EXAMPLE:4-( 1-Methylheptyloxy )phenyl 4'-((S)-2-methylbutyl)biphenyl-4-carboxyla te (S) form. USE:An electro-optical display material. Especially a ferroelectric liquid crystal material having excellent response and memory. PREPARATION:An optically active carboxylic acid shown by formula V is reacted with thionyl chloride to give an acid chloride, which is then reacted with an optically active phenolic derivative shown by formula VI in the presence of a base (e.g. pyridine) to give a compound shown by formula I.
