尾链类型对液晶分子近晶相态引入的影响(英文)

Influence of Tail Types on Smectic Phase Induction in Two Kinds of Liquid Crystal Molecules

研究了分子结构中不同尾链类型对向列相液晶分子液晶相态转变为近晶相的影响。设计合成了两种不同类型的液晶分子,它们的液晶相态采用热台偏光显微镜以及差示扫描量热仪进行研究。结果表明,卤素的引入是使向列相液晶分子相态转变为近晶相的有效方法。

The action on induction smectic phases in nematic molecules with different tail types of liquid crystal molecules were researched.Two types of molecules were synthesized and their mesomorphic phase behavior was researched with polarized light microscopy(PLM) and differential scanning calorimetry(DSC).From the results we could find that introducing halogen is an effective way to induce smectic phases in nematic mesogens.
