Organosilicon heterocycles, a class of important cyclic compounds, can be used for various applications such as catalysis, precursors of molecular transformation, electron transport and light-emitting materials. However, synthesis of such compounds in solution has been challenging. In this study, we developed a novel reaction on a gold surface. Silole (C4Si) derivatives and disila-cyclooctene (C6Si2) bridged nanoribbon structures were obtained through the on-surface reactions between silicon atoms and dibrominated molecules at the bay and peri positions, respectively. Our findings show a great potential to deal with heavy group 14 elements in various low-dimensional Si-incorporated nanostructures. Figure.
