SYNTHESIS AND SOME PROPERTIES OF 3-FLUORO-4-CYANOPHENYL 4 prime -n-ALKYLBENZOATES.

A series of 3-fluoro-4-cyanophenyl 4 prime -n-alkylbenzoates, which show monotropic nematic phases, was prepared and their transition temperatures and melting enthalpies were measured. The 3-fluoro-4-cyanophenyl 4 prime -n-propylbenzoate, 3-chloro-4-cyanophenyl 4 prime -n-propylbenzoate and 4-cyanophenyl 4 prime -n-propylbenzoate were mixed with a nematic mixture (A) of 4-n-alkoxyphenyl 4 prime -n-alkylcyclohexane-1 prime -carboxylates. 3-Fluoro-4-cyanophenyl 4 prime -n-propylbenzoate decreases the N-I transition temperature less, increases the birefringence more, and increases the bulk viscosity less than 3-chloro-4-cyanophenyl 4 prime -n-propylbenzoate, and reduces the threshold voltage to the greatest extent. The dielectric anisotropies of 3-fluoro-4-cyanophenyl 4 prime -n-propylbenzoate and 4-cyanophenyl 4 prime -n-propylbenzoate determined from a series of solutions of the compounds in nematic mixture (A) are 35. 9 and 29. 6, respectively.
