For the development of the stimuli-responsive electro-optic devices which can be controlled from a light scattering state to a transmittance state reversibly, a supramolecule based on photo-responsive azobenzene mesogens tethered to a benzene-1,3,5-tricarboxamide (B-3AZ) core was newly synthesized. The liquid crystal physical gels (LCPGs) were fabricated by introducing the B-3AZ supramolecules into the nematic liquid crystal (NLC) medium. The prepared LCPGs exhibited that the light scattering of the LCPGs can be converted to a transmittance state at lower driving voltage (22 V). Furthermore, it was demonstrated that the rewritable photo-responsive B-3AZ LCPG films can be remote-controlled by the photoisomerization of the azobenzene moieties under the UV-vis light. This work was supported by Ministry of Trade, Industry, and Energy (20011031).
