摘要：

Binary mixtures were prepared from an azobenzene derivative and a liquid-crystal (LC) compound that exhibits smectic C (SmC) and bicontinuous cubic (Cub bi) LC phases. Reversible switching between the two phases in response to UV-light irradiation was observed. This light-driven SmC-to-Cub bi transition is the first example showing the increased dimensionality of molecular ordering with isomerization of azobenzenes (see figure).
