We report on the design and synthesis of a new disc-like liquid crystal based on a 3, 5- dicyano-2, 4, 6-tristyrylpyridine core. The mesogenic behavior was investigated by differential scanning calorimetry, polarized-light optical microscopy, and X-ray diffraction. The disc-like structure self-assembles intoa hexagonal columnar mesophase and, due to the permanent dipole exhibited by the isolated molecule, the stacking along the columnar axis ...
