フォトリフラクティブ強誘電性液晶用光導電性キラルドーパントの比較

抄録

A series of photoconductive chiral compounds was added to ferroelectric liquid crystal blends to investigate the efficiency on the photorefractive effect. Using the samples, physical properties such as dielectric relaxation phenomena and photorefractive characteristics were investigated. We confirmed the existence of two response modes (Goldstone mode and Soft mode) observed in the Chiral Smectic C phase, and examined the influence on photorefractive properties combined with the orientation state. In addition, four types of photoconductive chiral compounds were prepared, and photorefractive properties of those samples were compared.
