TLDR
This review summarizes the major progress in the field, including the principles that permit atomically precise synthesis, new types of atomic structures, and unique physical and chemical properties ofatomically precise nanoparticles, as well as exciting opportunities for nanochemists to understand very fundamental science of colloidal nanoparticles.Abstract:
Colloidal nanoparticles are being intensely pursued in current nanoscience research. Nanochemists are often frustrated by the well-known fact that no two nanoparticles are the same, which precludes the deep understanding of many fundamental properties of colloidal nanoparticles in which the total structures (core plus surface) must be known. Therefore, controlling nanoparticles with atomic precision and solving their total structures have long been major dreams for nanochemists. Recently, these goals are partially fulfilled in the case of gold nanoparticles, at least in the ultrasmall size regime (1–3 nm in diameter, often called nanoclusters). This review summarizes the major progress in the field, including the principles that permit atomically precise synthesis, new types of atomic structures, and unique physical and chemical properties of atomically precise nanoparticles, as well as exciting opportunities for nanochemists to understand very fundamental science of colloidal nanoparticles (such as the s...read more

Structure of Au15(SR)13 and its implication for the origin of the nucleus in thiolated gold nanoclusters.
TL;DR: An extensive exploration of possible isomers by density functional theory arrives at a novel structure for Au15(SR)13 with high stability and whose optical absorption characteristics match those of the experiment, which suggests that Au15 (SR) 13 is a transitional composition from an [Au(I)-SR]x polymer such as Au10( SR)10 to larger Aun(SRm (n > m) clusters that have only the staple motifs.

Interlocked Catenane-Like Structure Predicted in Au24(SR)20: Implication to Structural Evolution of Thiolated Gold Clusters from Homoleptic Gold(I) Thiolates to Core-Stacked Nanoparticles
TL;DR: It is concluded that the tetrahedral Au(4) motif is a prevalent structural unit for small-sized RS-AuNPs with relatively low Au/SR ratio, and Calculations of electronic structures and UV-vis absorption spectra of Au(24)(SR)(20) and larger RS-NPs show that the ligand layer can strongly affect optical absorption behavior of RS- aiNPs.
