| Outline of Final Research Achievements |
In this study, we focus on a group of compounds called carbones (divalent carbon(0) compounds), which are expected to be new carbon ligands, and synthesize various polynuclear gold(I) complexes utilizing two lone pairs (LPs) of electrons at the central carbon atom to create luminescent metal complexes through the intramolecular gold(I)-gold(I) interactions. Specifically, we synthesized a dinuclear Au(I) complex combining a carbon ligands stabilized by a sulfur atom, which are successfully synthesized in our laboratory, and an N-heterocyclic carbene (NHC) ligands and screened their luminescent properties. As a result of various investigations, it was confirmed that the dinuclear gold(I) complex with NHC gold(I) ions coordinated to the central carbon of bisiminosulfanecarbon(0) emits blue light.
