| 摘 要： | ４．４’－双－（反式－对正戊基环己基）联苯（５ｃｐｐｃ５）具有熔点低，清亮点高的特点；因此，它的中介相温度很宽。本文提出一种通过三步反应合成５ｃｐｐｃ５的新路线，详细地讨论了这种液晶的合成方法以及有关影响反应的因素，并用红外、核磁、紫外、质谱等方法测定了该液晶的化学结构．研究了该化合物的热力学性质和偏光织构图。

| Abstract: | A new technological scheme in three steps is presented for the synthesis of the liquid crystal 5CPPC5 which has. a series of good qualities such as lower melting point, higher clean point value and 'broad-range. mesophasp. etc. The synthesis method and various affecting factors are discussed.,in more detail. The chemical structure was determined by IR,. .NMR, MS, and UV methods Its thermodynamic characteristics and textures were also investigated. |
