The visible‐light‐induced conversion of heptacene precursors to heptacene is described. The photoirradiation of the inner region of a mono‐α‐diketone‐type heptacene precursor crystal resulted in characteristic heptacene absorption peaks, indicating that the single‐crystal interior provided a reaction site isolated from the external environment thus preventing oxidation of unstable products. More information can be found in the Communication by H. Hayashi, S. Masuo, H. Yamada, et al. on page 15079.
