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.^[4]
