ABSTRACT:
The present invention provides novel optically-active aliphatic .beta.-halogen substituted carboxylic acid 4'-(4-alkoxybenzyloxy)biphenyl thioester compounds of the general formula: ##STR1## wherein R represents a straight-chained alkyl radical having C.sub.2 to C.sub.10 carbon atoms and X represents a halogen atom, and a process for the preparation thereof. The novel biphenyl thioester compounds provided according to the present invention are usable as a dopant or a base material for liquid crystal blending, thereby improving the properties of LCD.
