Syntheses of new 'large core' discogens based on the triphenylene, azatriphenylene and hexabenztrinaphthylene nuclei

Abstract
We have synthesized new discogens based on polyphenylated triphenylene, polyphenylated azatriphenylene and hexabenztrinaphthylene. A procedure for the extension of the aromatic core by Suzuki coupling is described, which minimizes competitive reductive dehalogenation.
