Author Affiliations +
We designed and synthesized a novel type of a cyclic compound containing azobenzene and binaphthyl moieties. The most significant characteristic of the compound is to possess a reversible change in a dihedral angle of a binaphthyl moiety by means of photoisomerization of the azobenzene moiety. Furthermore, the compound shows change in a twisting motion in a solution, a neat film, and a liquid-crystalline host by alternating irradiation of UV and visible light.
