We newly designed and synthesized a discotic supramolecule based on benezene-1,3,5-tricarboxamide (B9AZ) containing the photo-responsive azobenezene (AZ) mesogens. Based on the experimental results, it was realized that the programmed B9AZ formed the low-ordered hexagonal columnar liquid crystal (LC) phase, the highly ordered lamello-columnar LC phase, and the lamello-columnar crystal phase. Because the shape and color of the robust hierarchical B9AZ films were tuned by the conformational changes of azobenezene moiety in the B9AZ, we successfully demonstrated the remote-controllable 3D actuation and rewritable films by tuning the wavelength of light.
