with their chemical structure. The l-(4-alkanoylphenyl)-4-trans-alkylcyclohexanes as well as the l-(4-alkanoylphenyl)-4-(rani-alkan-oylcyclohexanes show nematicphases. In contrast to laterally substituted compounds, these ketones have clearingpoints which are higher than those of the corresponding hydrocarbons. Another advantage of these nematogens is the ease of synthesis.
