ABSTRACT The development of LC monophenyl unit is of a great interest for reach low cost LC materials. The aim of this work was to demonstrate the possibility to obtain monomer incorporating single phenyl unit for LC field. We report the synthesis and the characterization of acrylic monomers in fluorinated series which differ by the lengthening of the hydrocarbon spacer linking the acrylic part to
摘要 LC 单苯基单元的开发对于实现低成本的 LC 材料具有重要意义。这项工作的目的是证明获得包含单个苯基单元的单体用于 LC 领域的可能性。我们报告了氟化系列中丙烯酸单体的合成和表征,它们的不同之处在于将丙烯酸部分连接到“介晶”核心的烃间隔基的延长。LC 行为由 DSC 和 POM 装置确定。该烃间隔层长度的增加显着减小了近晶型中间相的跨度。对于长间隔,没有观察到介晶现象。
