Abstract

The arylthiolated Au₂₅(F-Ph)₁₈^- nanocluster is synthesized and characterized. Ligands avoid distortion of the geometric structure, limit the Jahn-Teller effect, and protect the nanocluster from oxidization. The low energy gap (HOMO-LUMO) of the synthetic clusters enables photocatalytic oxidative functionalization reactions mediated by near-infrared light (850 nm).
