ABSTRACT:
2-phenylpyridine derivatives represented by the general formula: ##STR1## wherein when Y is R--, Z is one of R--, RO--, ##STR2## when Y is RO--, Z is one of straight chain pentyl, ##STR3## and when Y is one of Z is one of R--, RO-- and --CN; when Y is --CN, Z is one of RO--, ##STR4## and R is a straight chain alkyl group from 1 to 12 carbon atoms, are disclosed. The 2-phenylpyridine derivatives in accordance with the invention are particularly well-suited for use in nematic liquid crystal compositions for reducing the steepness and response time of the liquid crystal compositions in a liquid crystal display device.
