摘要

PROBLEM TO BE SOLVED: To obtain a new carboxylic acid ester compound useful as an antiferroelectric liquid crystal compound and a component for an antiferroelectric liquid crystal compound, maintaining an existing spontaneous polarization magnitude, having an enlarged tilt angle. ;SOLUTION: This carboxylic acid compound is shown by formula I [R is a 3-20C (polyfluoro)alkyl, etc.; X is a single bond or O; A¹ and A² are each 1,4-phenylene, biphenyl-4,4'-diyl, etc., and at least one of them is 1,2,3,4- tetrahydronaphthalene-2,6-diyl, etc.; Y is COO, CH₂CH₂, etc.; (n) is 2-8] such as 6-(4-decyloxybiphenyl-4'-carbonyloxy)-1,2,3,4-tetrahydronaphthalene-2-carboxylic acid-4-heptyl ester. The compound of formula I in which Y is COO is obtained by reacting a compound of formula II (Ph is phenyl) with a compound of the formula HOCH(C_nH_2n+1)2 to give a compound of formula III, reducing the compound with hydrogen to give a compound of formula IV and reacting the compound with a compound of formula V.;COPYRIGHT: (C)1997,JPO
