Monocarboxylate-protected two-electron superatomic silver nanoclusters with high photothermal conversion performance

Abstract

The first series of monocarboxylate-protected superatomic silver nanoclusters was synthesized and fully characterized by X-ray diffraction, Fourier-transform infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS) and electrospray ionization mass spectrometry (ESI-MS)....

Atom-Precise Ligated Copper and Copper-Rich Nanoclusters with Mixed-Valent Cu(I)/Cu(0) Character: Structure–Electron Count Relationships

“…The large size of the hexagonal base allows through-cage bonding between the two axial atoms, reinforcing its compact nature. Such a flat hexagonal bipyramidal structure has been reported for other noble-metal two-electron species [39][40][41]. Clusters 9 and 10 have a much larger nuclearity and a more complex structure with a large number of Cu(I) centers in their protecting shell.…”

Recent advances in synthesis and properties of silver nanoclusters

“…Following this work, 9-anthracene carboxylate, a bulky monocarboxylate, and different phosphines were used to synthesize two-electron [Ag 16 (L) 8 (9-AnCO 2 ) 12 ] 2+ clusters. 58 Its structure features an [Ag 8 @Ag 8 ] 14+ core-shell structure, with an [Ag 8 ] 6+ superatomic inner core adopting an unprecedented structure showing a distorted hexagonal bipyramidal structure. The outer Ag 8 shell is composed of the unique "Ag(PR 3 )-AnCOO-Ag(PR 3 )" staple motifs.…”

Polyoxometalate-mediated syntheses of three structurally new silver clusters

“…nanoclusters have attracted increasing attention from the scientific community due to their novel aesthetic structures, unique physicochemical properties and widespread application, 1–6 including their promising applications in various fields like catalysis, photochromism, chirality, biomedicine, and chemical sensing, etc . 7–14 The synthesis of Ag clusters is inextricably linked to the involvement of surface-protecting organic ligands, mainly thiolate, 15–19 phosphine, 20–22 alkynyl, 23–25 and amide ligands 26 or appropriate combination of these ligands, 27 which can offer more possibilities for the structure and properties of Ag clusters. In addition to the adjustable ligand type, the introduction of structure-directing agents like anionic templates has also largely contributed to the construction of high-nuclearity Ag clusters, and the anion-template synthetic strategy has become a popular route for making novel Ag clusters.…”
