The present invention relates to the synthesis of polycyclic aromatic compounds. Compounds such as terrylene or quaterrylene may now be prepared in relatively high yield by reaction of naphthalene or perylene via Scholl-type coupling in the presence of a superacid and an oxidant in an inert solvent.

Scalable synthesis of quaterrylene: Solution-phase 1H NMR spectroscopy of its oxidative dication
Quaterrylene is prepared in a single reaction and high yield by Scholl-type coupling of perylene, utilizing trifluoromethanesulfonic acid as catalyst and DDQ or molecular oxygen as oxidant. Dissolution in 1 M triflic acid/dichloroethane with sonication yields the aromatic quaterrylene oxidative dication, which is characterized by its 1H NMR spectrum.
