Generalizable Organic-to-Aqueous Phase Transfer of a Au₁₈ Nanocluster with Luminescence Enhancement and Robust Photocatalysis in Water.

ABSTRACT: For the majority of gold nanoclusters (NCs), their water insolubility, low photoluminescence (PL) intensity, and less understood photostability are three critical factors that limit their application in the biomedical and photocatalysis fields. In this study, we report a polymer wrapping method for phase transfer of organic soluble NCs into aqueous phase without degrading the electronic and optical properties, and such materials are further demonstrated for robust photocatalysis in water. We first synthesized a Au₁₈(DMBT)₁₄ NC (DMBT = 2,4-dimethylbenzenethiolate) and found that the aromatic ligands confer a greatly enhanced antioxidation capability of the NC compared to the Au₁₈(CHT)₁₄ counterpart (CHT = cyclohexanethiolate), with the critical ro
