A series of novel push-push I and push-pull II carbene-stabilized complexes of phosphorus(V) fluorides bearing substituents with liquid-crystalline properties were synthesized by the oxidative addition of difluoroamines to phosphorus(III) halides. These octahedral complexes were characterized by NMR spectroscopy and X-ray analysis.

2-phenyl-5-(4'-trans-cyclohexyl) phenyl pyrimidine derivatives represented by the general formula: STR1 wherein R is a straight chain alkyl group having 1 to 10 carbon atoms; X is CN or F; Y is F or H; Z is F or H; and when X is F, at least one of Y and Z is H; and the cyclohexane ring is a trans isomer, exhibiting a nematic phase and having a high nematic phase-isotropic liquid phase transition temperature (N-I Point) and large positive dielectric constant anisotropy (Δε). The pyrimidine derivatives may be included in liquid crystal compositions for improved display devices having a wide temperature range, including a high N-I point, a low threshold voltage and a low driving voltage.
