The well-defined hierarchical supramolecules can be organized for the fabrication of remote-controllable actuation and rewritable films. We newly synthesized a benezene-1,3,5-tricarboxamide (BTA) derivative (abbreviated as BTA9AZO) containing the photo-responsive azobenezene (AZO) mesogens. Based on the experimental results, it was realized that the programmed BTA9AZO 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 BTA9AZO films were remote-controlled by the conformational changes of azobenezene moiety in the BTA9AZO, we successfully demonstrated the remote-controllable 3D actuation and rewritable films by tuning the wavelength of light.
