Abstract
The synthesis and characterization of seven polysubstituted 9-arylcarbazole derivatives is described. The influence of the number of chains peripherally bonded to the core, as well as the length of the chains, on the mesophase behaviour of the synthesized systems has been studied. The nature of the linking group between the core and the peripheral chains has also been considered. One of these compounds displays liquid crystalline behaviour, as confirmed by optical polarizing microscopy, differential scanning calorimetry and X-ray diffraction, being the first carbazole-based lamellar liquid crystal system reported in the literature.
