PURPOSE: To obtain a new compound useful for a ferroelectric liquid crystal display device having excellent switching characteristics, quick response and small temperature dependency of optical response speed.
CONSTITUTION: This compound is expressed by the formula R-A-Y-X {R is a 1-20C alkyl, H or F; A is A1, A1-Z1-A2 or A1-Z1-A2-Z2-A3 (A1 to A3 each is a substituted 1,4-phenylene, pyrimidine-2,5-diyl, etc.; Z1 and Z2 are each single bond, COO, OCO, CH2O, CH=CH, C≡C, etc.); X is 2-bicyclo[2,2,1]heptyl, 1- tricyclo[3,3,1,13.7]decyl, etc.}, e.g. 2-(1-tricyclo[3,3,1,13.7]decylacetic acid 4-(5- decylpyrimidin-2-yl)phenyl ester. The compound of the formula is produced e.g. by reacting 4-(5-decylpyrimidin-2-yl)phenol with (1-tricyclo[3,3,1,13.7]decyl) acetic acid, 1,3-dicyclohexylcarbodiimide and 4-pyrrolidinopyridine.
