Dispersion of 4-Cyano-4'-n-octylbiphenyl (8CB) mixed with the azobenzene derivative in a cetyltrimethylammonium bromide (CTAB) solution often resulted in the observation of fibrous and disk-shaped liquid crystals. The fibers extended under UV light and shrunk under Visible light, while the disks deformed into fingering shapes under UV light and reverted to disks under vVisible light. The deformation speed and the number of fingers could be controlled by the light intensity. The deformation was considered to be caused by the cis-trans isomerization of the azobenzene derivative, which should modulate the molecular alignment in the interface.
