Kinetically Controlled Synthesis of Highly Emissive Au₁₈SG₁₄ Clusters and Their Phase Transfer: Tips and Tricks.

ABSTRACT: Glutathione (GSH) protected gold nanoclusters (Au _n SG _m NCs) have been attractive because of their novel properties such as enhanced luminescence and band gap tunability at their quantum confinement region (below ∼2 nm). Initial synthetic routes of mixed-size clusters and size-based separation techniques had latter evolved toward atomically precise nanoclusters via thermodynamic and kinetic control routes. One such exemplary synthesis taking the advantages of a kinetically controlled approach is producing highly red-emissive Au₁₈SG₁₄ NCs (where SG = thiolate of glutathione), thanks to the slow reduction kinetics provided by the mild reducing agent NaBH₃CN. Despite the developments in the direct synthesis of Au₁₈
