摘要

为了制备快速响应的蓝相（BP）液晶电光器件，并研究其在不同电场频率下的响应，本文首先合成了双频液晶分子（DFLC），将其加入蓝相母体液晶中，得到了可双频驱动的蓝相液晶（DF-BPLC）材料。利用偏光显微镜（POM）在不同频率的电场下观察其织构及相变行为，通过添加DFLC，可以调控BP温域。在低频电场下，由于电场取向作用及DFLC的弯曲结构和挠曲电效应可使得BP温域得到拓宽。但在高频电场下，BP温域有所减小。所制备DF-BPLC材料既具有频率响应特性又具有优异的电光性能，在光电器件中有很好的应用前景。

Abstract

In order to obtain fast response electro-optic devices

a dual-frequency-driven blue phase liquid crystal (DF-BPLC) was obtained through preparing dual-frequency liquid crystal molecules and adding into a blue phase host. The texture and phase transition behavior of the DF-BPLC were observed by polarizing microscopy (POM) at different electric field frequencies

and it was found that it could have a great influence on the temperature range of blue phase (BP). Under low frequency electric field

the BP temperature range of DF-BPLC can be broadened under the effects of electric field orientation

bending structure and flexoelectricity of DFLC. The prepared DF-BPLC material exhibits not only frequency responsive characteristic

but also excellent electro-optic property

which may have great application prospects in optoelectronic devices.
