Synthesis and Properties of Chiral Liquid Crystalline Polymers

手性侧链分子型液晶材料由于具有许多独特的物理性质,例如具有选择性光反射、光电反射效应等,因而在航空航天、军事电子科技等领域中有着重要的应用意义。本论文首先合成三种新型液晶单体:M1、M2和M3,然后将其接枝共聚到聚甲基氢硅氧烷的主链上,以合成一种新型手性侧链液晶聚合物。这种高分子手性液晶聚合物,在电子信息、数据存储、非线性应用光学器件及光电子器件等许多领域中,具有重要的潜在应用前景。

Chiral-side-chain(CSC)molecular liquid-crystal possesses many unique physical properties like selective light reflection and photoelectric reflection,which have played significant roles in several fields such as aerospace,military electronic technology etc.In this article,three new type liquid-crystal monomers:M1,M2 and M3,are synthesized at first.And then they are grafted to copolymerize onto main chains of poly-methyl-hydrosiloxane to synthesize a new type CSC liquidcrystal polymer,which may have an important potential application in many fields such as electronic information,data storage,nonlinear-applied optical and optoelectronic devices and so on.
