Octacene is an organic compound and a polycyclic aromatic hydrocarbon and the eighth member of the acene or polyacene family of linear fused benzene rings. Its сhemical formula is C₃₄H₂₀.

Synthesis

In 2010, the Bettinger group reported a photochemical synthesis of octacene and nonacene, utilizing a cryogenic matrix-isolation technique to stabilize these highly reactive acenes. This approach requires precursors containing a double α-diketone bridge to enable the formation of octacene and nonacene.
