  • The Synthesis and Some Physical Properties of New Laterally Substituted Phenyl Ethers Containing atrans-1,4-Disubstituted Cyclohexane Ring
    作者:Stephen M. Kelly、Hanspeter Schad
    DOI:10.1002/hlca.19850680331
    日期:1985.5.15
    The synthesis, liquid-crystal transition temperatures, and some physical properties of a variety of substituted phenyl ethers, most of which incorporate a lateral substituent, are reported. Many of the liquid crystals described exhibit nematic phases with negative dielectric anisotropy at elevated temperatures. The relationship between the nature of the lateral substituents and the observed liquid

    with their chemical structure. The l-(4-alkanoylphenyl)-4-trans-alkylcyclohexanes as well as the l-(4-alkanoylphenyl)-4-(rani-alkan-oylcyclohexanes 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.

    Liquid crystals with negative Δϵ can be obtained by incorporating a cyano group in the terminal alkyl substituent or in an ethylene bridge between the cyclic units of the rigid core. The clearing points of such compounds are higher than those of the corresponding derivatives where the cyano group is laterally attached to a phenyl moiety. In compounds where both cyclic units of the rigid core are cyclohexyl
    通过在末端烷基取代基中或在刚性核的环状单元之间的乙烯桥中引入氰基,可以得到具有Δ△负的液晶。这种化合物的透明点高于氰基侧向连接于苯基部分的相应衍生物的透明点。在刚性核的两个环状单元均为环己基的化合物中,与氰基苯基衍生物相比,这种取代方式可导致对ϵ⟂的最佳贡献。
