For the fabrication of well-defined hierarchical superstructures on the different length scales via the self-assembly processe, programmed asymmetric amphiphile was newly designed and synthesized a dual photo-functionalized hierarchical superstructure (abbreviated as AzoDA) containing azobenzene and diacetylene groups. 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 AzoDA 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. |
