, (2008/06/13)
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 --CN; and when Y is one of STR4 Z is one of R--, RO-- and --CN; when Y is --CN, Z is one of RO--, STR5 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.

New liquid-crystalline 2-(4-alkylphenyl)-5-alkylpyridines were synthesized by the reaction of 2-(4-alkylphenyl)-1-lithio-1,2-dihydropyridines with alkyl bromides.The compounds obtained have relatively low melting points and narrow temperature ranges of the existence of a nematic meso phase; the thermal stability of the meso phase is determined by the lenght of the alkyl group in the pyridine and benzene parts of the molecule.
