Synthesis and solution isomerization of water-soluble Au₉ nanoclusters prepared by nuclearity conversion of [Au₁₁(PPh₃)₈Cl₂]Cl.

ABSTRACT: Water-soluble gold nanoclusters (AuNCs) are popular in biomedical applications such as bioimaging, labelling, drug delivery, and biosensing. Despite their widespread applications, the synthesis of water-soluble phosphine-capped AuNCs is not as straightforward as their organic-soluble equivalents. Organic soluble phosphine-passivated [Au₉(L)₈]³⁺ are 6-electron closed-shell AuNCs that are generally prepared via the reduction of a phosphine-Au(I) complex by NaBH₄. A similar approach attempted for the water-soluble ligand triphenylphosphine monosulfonate (TPPMS) using [AuTPPMS]Cl resulted in a mixture of cluster sizes that required gel electrophoresis or fractional precipitation to isolate the Au₉ product. In this work, we report th
