PA57 Effect of Addition of Azobenzene Derivatives on Aggregation Structures in Bicontinuous Cubic Liquid Crystalline Mixtures

Abstract

Bicontinuous cubic (Cub_bi) liquid crystalline phases have self-organized structure with three-dimensional network. A famous compound called ANBC-22 shows two types of Cub_bi phases (Ia3d and Im3m). In this study, we found that when azobenzene conpounds are added, the structure of Cub_bi phase significantly depends on the molecular structure of the additives and its amount in the binary mixture. This result is important for discussion on the mechanism of Cub_bi-Cub_bi phase transition.
