Large, soluble polycyclic aromatic hydrocarbons (PAHs) have been synthesized using Zr-mediated and Stille-type biphenylation reactions. Both the Zr and Stille methodologies have been adopted to incorporate tert-butyl substituents, permitting the directsynthesis of alkylated PAHs that are much more soluble than their unsubstituted analogues. To demonstrate the utility of these methods and the importance

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.
