phenanthrene-substituted aryl triflates proceeded regioselectively. The findings inspired us to develop a rapid and efficientsynthesis of polybenzoacene derivatives. This study not only allows the transformation of phenyl triflates but also discloses a new retrosynthetic strategy towards fused polyaromatics, especially polybenzoacenes.

intramolecular InCl3/AgNTf2‐catalyzed regioselective domino benzannulationreaction of buta‐1,3‐diynes to build irregular nanographenes. Different nanographene compounds were easily obtained in moderate to high yields through careful design of the precursor compounds. This new domino reaction was successfully applied to a fourfold alkyne benzannulation of dimethoxy‐1,1′‐binaphthalene derivatives to arrive

A series of ladder-type graphene ribbon oligomers have been synthesized through DDQ/acid-mediated oxidative cyclization. The oligomers present a bright blue light emission, and the new oligomers were clearly characterized by NMR and MALDI-TOF.
