In this study, a novel core fragment for discotic liquid crystals was discovered, which is composed of an unusual contorted polycyclic aromatic hydrocarbon, Rubicene. The Rubicene derivatives synthesized were thermally stable and showed columnar mesophases at room temperature, as confirmed by polarising optical microscopy, differential scanning calorimetry, and small-angle X-ray scattering.
Rubicene, an unusual contorted polycyclic aromatic hydrocarbon, was realized to function as a novel core fragment for discotic liquid crystals. The central pi-conjugated motif was prepared from dialkoxyiodobenzene via Sonagashira coupling followed by pentannulation and Scholl cyclodehydrogenation. The synthesized rubicene derivatives were found to be thermally stable and exhibit enantiotropic columnar mesophases. The columnar arrangement of these derivatives has been validated using polarising optical microscopy, differential scanning calorimetry & small-angle X-ray scattering.
