Abstract A triphenylene-based reactive mesogen molecule (abbreviated as TPBRM) was newly designed and synthesized for the fabrication of striped walls during photopolymerization in the anisotropic liquid crystal (LC) medium. From thermal, scattering and microscopic results, it was found that TPBRM formed three ordered structures: a columnar hexagonal LC phase, a tilted columnar hexagonal LC phase and a highly ordered columnar oblique crystal phase. While the dimensions of the striped wall morphologies were determined by the patterned photomasks, the microscopic molecular orientations in the hierarchical superstructures were self-organized with the support of surface anchoring forces. Regardless of the photomask direction, the long axis of self-assembled columns in the striped walls was normal to the surface alignment direction. In addition, it was realized that the shapes of water drops as well as the surface contact angles of the surface water can be controlled by the hierarchical superstructures and morphologies of the polymerized TPBRM networks. The fabricated hierarchical superstructures and morphologies can allow us to develop electronic and microfluidic devices.
