Abstract

In this study, a polymerizable chiral dopant end-capped with menthyl group was synthesized. The solubility of the polymerizable chiral dopant in a mesogenic host was also studied. The film with left-handed broadband reflective capability was prepared via employing the chiral dopant and a bifunctional mesogenic compound as the polymerizable monomers. To enhance the reflection of the broadband reflective film, two films that reflected left-handed circularly polarized light and right-handed circularly polarized light, respectively, were superimposed to obtain a composite film. The reflection of the composite film for the light with the wavelength between about 800 and 1150 can exceed 60%.

摘要

在这项研究中，合成了一种用薄荷基封端的可聚合手性掺杂剂。还研究了可聚合手性掺杂剂在介晶主体中的溶解度。采用手性掺杂剂和双功能介晶化合物作为可聚合单体制备了具有左手宽带反射能力的薄膜。为了增强宽带反射膜的反射，将分别反射左旋圆偏振光和右旋圆偏振光的两层膜叠加以获得复合膜。复合膜对波长在800-1150之间的光的反射率可超过60%。
