A research team led by Professor Chi-Ming Che and Dr Jun Yang has resolved a long-standing fundamental problem in the field of metal-metal closed-shell interaction. This work has been published in the journal Proceedings of the National Academy of Sciences (PNAS).
Metal-Metal closed-shell interaction, also known as metallophilicity, has a huge impact in diverse fields of chemistry, such as supramolecular chemistry and organometallic chemistry. Early reports on metallophilicity could be traced back to the 1970s. Many leading theoretical chemists around the world made contributions in the field, such as Roald Hoffmann (1981 Nobel Laureate in Chemistry), Pekka Pyykkӧ, etc.. Metallophilicity is important in the fabrication of self-assemblies by transition metal complexes, which has demonstrated profound applications in organic semiconductors, bio-sensing and functional optoelectronic materials.
