We report the synthesis and characterization of novel bistetracenes, an unconventional, linearly extended conjugated core with eight fused rings. Also described are bisoligoacenes. In general, the properties and stability of large polycyclic aromatic hydrocarbons (PAHs) strongly depend on the mode of ring annellation and the topology of their it-electron systems, which are usually associated with the resonance stabilization energy in large PAHs.
