Abstract

Photorefractive liquid crystal blends exhibiting the flexoelectric effect were prepared, and the photorefractive effect, dielectric properties, and optical properties of these materials were investigated. These blends comprised mixtures of smectic liquid crystals with chiral photoconductive compounds and an electron-trap reagent. Depending on the molecular structure of the chiral compound, these mixtures showed either only flexoelectricity or both flexoelectricity and ferroelectricity. The former mixtures exhibited a faster and larger photorefractive effect than the latter ones.

含有乳酸和羟基丁酸结构的光导手性掺杂剂的铁电和柔性电液晶共混物的光折变效应

制备了具有挠曲电效应的光折变液晶共混物，并对其光折变效应、介电性能和光学性能进行了研究。这些混合物包括具有手性光导化合物的近晶液晶和电子陷阱试剂的混合物。根据手性化合物的分子结构，这些混合物要么只显示柔韧电性，要么同时显示柔韧电性和铁电性。前者比后者具有更快更大的光折变效应。
