Isomerism in Au28(SR)20 Nanocluster and Stable Structures.
Yuxiang Chen,Chong Liu,Qing Tang,Chenjie Zeng,Tatsuya Higaki,Anindita Das,De-en Jiang,Nathaniel L. Rosi,Rongchao Jin +8 more
TL;DR: The ligand-induced, thermally reversible isomerization between two thiolate-protected 28-gold-atom nanoclusters is reported and the intriguing ligand effect in dictating the stability of the two Au28(SR)20 structures is further investigated via dispersion-corrected density functional theory calculations.
Journal ArticleDOI
Generation of Singlet Oxygen by Photoexcited Au25(SR)18 Clusters
Hideya Kawasaki,Hideya Kawasaki,Santosh Kumar,Gao Li,Chenjie Zeng,Douglas R. Kauffman,Junya Yoshimoto,Yasuhiko Iwasaki,Rongchao Jin +8 more
TL;DR: In this article, the authors demonstrate that 1O2 can be efficiently produced through direct photosensitization by Au25(SR)18-clusters (H−SR = phenylethanethiol or captopril) without using conventional organic photosensitizers under visible/near-IR (532, 650, and 808 nm) irradiation.
Journal ArticleDOI
Crystal structure and electronic properties of a thiolate-protected Au24 nanocluster
TL;DR: The X-ray structure of a charge-neutral Au24(SCH2Ph-(t)Bu)20 nanocluster is reported, which features a bi-tetrahedral Au8 kernel protected by four tetrameric staple-like motifs.
Journal ArticleDOI
Crystal Structure of Barrel-Shaped Chiral Au130(p-MBT)50 Nanocluster
Yuxiang Chen,Chenjie Zeng,Chong Liu,Kristin Kirschbaum,Chakicherla Gayathri,Roberto R. Gil,Nathaniel L. Rosi,Rongchao Jin +7 more
TL;DR: Comparison of the structure determination of a large gold nanocluster formulated as Au130(p-MBT)50 reveals an interesting phenomenon that a subtle ligand effect in the para-position of benzenethiolate can significantly affect the gold atom packing structure, i.e. from the 5-fold twinned Au55 decahedron to 20-fold Twinned Au 55 icosahedron.
Journal ArticleDOI
Gold tetrahedra coil up: Kekulé-like and double helical superstructures.
TL;DR: Two unique structures of gold clusters solved by x-ray crystallography, including Au40 and Au52 protected by thiolates, reveal anisotropic growth of the FCC lattice in the cluster regime, which provides implications for the important roles of ligands at the atomic level.
