Abstract |
Dendronized polymer (denpol) is newly designed and successfully synthesized by ring-opening metathesis polymerization (ROMP) of norbornene-based dendrons containing azobenzene-functionalized components and their self-assembly to produce the photomechanical work is systematically investigated. The uniaxially oriented film forms the well-ordered lamellar superstructure. The free-standing film is found to show the photorevesible actuating motion upon alternating the wavelength of irradiation light. The observation of peculiar bending direction from this material highlights that photomobile behavior can be precisely controlled in the defined manner by manipulating the hierarchical symmetry of the initial chromophore alignment. The photorevesible bending and unbending motion with a praogrammed direction will be beneficial for the practical application of the remote-controllable wireless actuator and light-switchable logic devices. This work was mainly supported by MOTIE and Mid-Career Researcher Program of Korea. |
