Lucky seven : Crystals of heptacene, which consists of seven linearly fused benzene rings, remain stable for at least 21 days in mineral oil and 24 h in degassed solution when the oligoacene is functionalized with phenyl and triisopropylsilylethynyl groups (see scheme). The right combination of functionalities makes this seven‐ring system the most stable functionalized heptacene synthesized to date.
