| Outline of Final Research Achievements |
Our group recently found a novel light-driven liquid crystalline phase transition of a one-dimensionally ordered smectic C (SmC) to a three-dimensionally periodic bicontinuous cubic (Cub_bi) phases for a binary mixture of a Cub_bi-phase-forming molecule with an azo adduct. This project has aimed at (i) revealing of the mechanism of the light-driven phase transition, and (ii) exploiting of new systems whose nano-structures and their structural dimensionalities can be controlled by light. Actually, the project has obtained the following outcomes: (1) Quantitative analysis of light-driven SmC to Cub_bi phase transition by time-resolved grazing-incidence small-angle X-ray scattering and birefringence measurements, and elucidation of the molecular-level mechanism, and (2) exploitation of three new systems exhibiting analogous light-driven phase transitions, and (3) additional accomplishments such as several fundamental contributions to physical chemistry of thermotropic Cub_bi phase.
