Through the incorporation of partially fluorinated and branched fluorinated end-groups of ferroelectric liquid crystals we aimed to examine the effects on physico-chemical structures and properties, and electrical switching behaviour for a family of compounds based upon the MHPOBC motif. We show that the nature of the terminal group strongly affects the liquid crystal behaviour and the thresholds associated with electro-optic switching. In this article we present the synthesis, transition temperatures, electro-optical measurements and X-ray diffraction studies for a series of compounds.
通过在铁电液晶中引入部分氟化和支化氟化末端基团,我们的目标是研究对基于MHPOBC骨架的一类化合物的物理化学结构、性质以及电场切换行为的影响。我们表明,末端基团的性质强烈影响液晶行为以及与电光切换相关的阈值。在这篇文章中,我们展示了系列化合物的合成、转变温度、电光测量以及X射线衍射研究。
