| Abstract: | The design and synthesis of a disc-like liquid crystalline compound using triphenylamine as a core has been achieved. The mesogenic properties were characterized by polarizing microscopy and differential scanning calorimetry and XRD studies. The compound existed as a hexagonal columnar mesophase. The fluorescence properties revealed the presence of intermolecular excimer formation. |
