Porous metal-organic frameworks have attracted tremendous research interest, because of the presence of tunable porous structures and site-isolated catalytic units. However, bottom-up on-surface synthesis of their inorganic counterparts, metal-inorganic frameworks (MIFs), is rarely demonstrated. Here, we report a facile epitaxial growth of one-dimensional (1D) porous metal-inorganic chains, gold–phosphorus chains (AuP chains), in which phosphorus magic clusters P4 are interconnected by Au atoms extracted from the underlying Au(110) surface. The atomic structure has been precisely revealed through the combination of low-temperature scanning tunneling microscopy, X-ray photoelectron spectroscopy, and density functional theory calculations. The growth process involves the formation of phosphorus dimers sitting at the bridge sites of the top rows of Au(110) (2 × 1) reconstructed surface at low coverage, followed by the etching of the phosphorus dimers and the transformation to 1D AuP chains with prolonged phosphorus deposition. Our findings provide a facile method for on-surface synthesis of 1D MIFs and pave the way for their potential applications in the future.
