, p. 253 - 258 (2007/10/02)
Four compounds with the general structure R-X-Y-CH2-CH2-Ph-CF3 were synthesized, where X is a 1,4-disubstituted trans-cyclohexyl ring, Y is a phenyl ring, and R is a n-alkyl group.The synthetic procedure is discussed and the structural assignments were confirmed by NMR spectroscopy.The liquid crystal behavior of these compounds was evaluated by DSC and polarizing microscopy.They might be used in fast switching liquid crystal mixtures.
KETONES-NEMATOGENS WITH MODERATE NEGATIVE DIELECTRIC ANISOTROPY AND HIGH CLEARING POINTS.

Anisotropic ketones whose rigid cores contain phenyl and cyclohexyl units were synthesized. The carbonyl group was incorporated either in the terminal substituents or in the link between the core units. The mesomorphic behavior of these ketones is described and correlated with their chemical structure. The 1-(4-alkanoylphenyl)-4-trans-alkylcyclohexanes as well as the 1-(4-alkanoylphenyl)-4-trans-alkanoylcyclohexanes show nematic phases. In contrast to laterally substituted compounds, these ketones have clearing points which are higher than those of the corresponding hydrocarbons. Another advantage of these nematogens is the ease of synthesis.
