| Abstract |
For the fabrication of optically tunable multifunctional thin films, was newly designed and synthesized a dual photo-functionalized hierarchical superstructure (abbreviated as AZDAA) containing azobenzene and diacetylene groups. Based on the combined experimental results with DSC, POM, SAXS and WAXD, we confirmed the phase behaviors and molecular packing structures. Since the photo-isomerization of the azobenzene moiety, the liquid crystalline phase was transformed from ordered smectic A (SmA) to disordered Isotropic (Iso) phase under the UV light. And due to the photo-polymerization of the diacetylene moiety in solid state, the thermos-reversible color changing was observed by irradiating UV light. We demonstrated the dual photo-functionalization of AZDAA as remote-controllable light shutter, photo-patterned thin film, and thermo-responsive color switch. This work was supported by, the MOTIE/KDRC 10051334, BRL 2015042417 and the BK21 Plus program. |
