The synthesis of large acenes via traditional solution-chemistry routes is hindered by their poor solubility and high reactivity under ambient conditions. Here, the authors demonstrate the on-surface formation of large acenes, via visible-light-induced photo-dissociation of α-bisdiketone molecular precursors on an Au(111) substrate.
