| Research Abstract |
We found that an oligo(o-phenylene) (OP), characterized by a cylindrical helical geometry, can act as a novel mesogen. The nematic liquid crystalline (LC) OP as a dopant also shows a high miscibility with discotic molecules. To our surprise, in the doped material, the 2D hexagonal lattice of the LCs fully aligns homeotropically relative to a glass substrate. Furthermore, some discotic LCs forming similar structures to OP generate a hexagonal columnar LC phase at room temperature, where the 2D hexagonal lattice entirely aligns homeotropically relative to various substrates. We noticed that the discotic molecules show an anisotropic transient microwave conductivity.
