Antiaromatic twinned triphenylene discotics showing nematic phases and 2-dimensional π-overlap in the solid state

Abstract

Construction of formally antiaromatic discotic twins based on dehydroannulene cores linked through non-adjacent positions on triphenylenes gives stable molecules with intriguing molecular and supramolecular properties and, unlike the majority of discotic triphenylenes and similar materials, the twins form nematic mesophases on heating.
