摘要

本文通过在倾斜螺旋胆甾相液晶中引入光敏手性分子，设计了一种光响应倾斜螺旋胆甾相液晶体系。在电场和光场的协同作用下，螺旋结构的选择性反射可以实现从可见光到近红外区域宽光谱动态域调控。倾斜螺旋结构的反射光谱调谐范围与体系初始螺旋扭曲力相关，通过调节手性材料的浓度，倾斜螺旋胆甾相液晶在电场作用下实现了从可见光到近红外区域约580 nm较宽光谱范围的反射带调节。同时，在固定电场下，通过调节非偏振紫外光场的功率获得了覆盖整个可见光区域以及近红外区域约530 nm的光谱调控，其中光调控特性主要取决于光场产生的热效应以及偶氮基团的光致异构效应。此外，由于倾斜螺旋结构的电场依赖性，通过调制电场的强度可以控制倾斜螺旋胆甾相液晶反射带光场调制区间。

Abstract

By introducing photosensitive chiral molecules into the heliconical cholesteric liquid crystal

a photoresponsive heliconical cholesteric liquid crystal system is designed. Under the synergistic effect of electric field and optical field

the selective reflection of the heliconical structure can be adjusted from visible light to near-infrared region. The tuning range of the reflection spectrum of the heliconical structure is related to the initial helical twisting power of the system. The heliconical cholesteric liquid crystal realizes a broad spectral range (about 580 nm) from visible light to near-infrared region under the modulation of electric field through adjusting the concentration of the chiral photosensitive molecule. Meanwhile

by modulating the power of the non-polarized ultraviolet light field

the tuning range (about 530 nm) of the heliconical cholesteric liquid crystal covering the entire visible light region and the near-infrared region is obtained under a fixed electric field. Such broad spectrum modulated by optical field mainly depends on the thermal effect of optical field and photoisomerization effect of azobenzene. In addition

due to the electric field dependence of the heliconical structure

the optical field modulation interval of the heliconical cholesteric liquid crystal reflection band can be controlled by electric field.
