Remarkable enhancement in ligand-exchange reactivity of thiolate-protected Au25 nanoclusters by single Pd atom doping.

چکیده
The effect of Pd doping on the ligand-exchange reactivity of Au(25)(SC(12)H(25))(18) was studied by comparing the ligand-exchange reactivity of [Au(25)(SC(12)H(25))(18)](-) and [PdAu(24)(SC(12)H(25))(18)](0) and the results clearly demonstrate that, regardless of the kind of incoming thiols and solvents, Pd doping greatly increases the rate of ligand exchange of Au(25)(SC(12)H(25))(18), indicating an enhanced ease of ligand exchange.

Importance of double-resonance effects in two-photon absorption properties of Au25(SR)18.
The two-photon absorption (TPA) cross-sections of small thiolate-protected gold clusters have been shown to be much larger than typical small organic molecules. In comparison with larger nanoparticles, their TPA cross-sections per gold atom are also found to be larger. Theoretical simulations have suggested that the large enhancement of these TPA cross-sections comes from a one-photon double-re...

The ligand exchange reaction between heteroatom doped (Pd, Pt) Au25(2-PET)18 (2-PET = 2-phenylethylthiolate) clusters and enantiopure 1,1′-binaphthyl-2,2′dithiol (BINAS) was monitored in situ using chiral highperformance liquid chromatography (HPLC). During the ligand exchange reactions, replacement of two protecting thiols (2PET) with one new entering BINAS ligand on the cluster surface occurs...
متن کاملContinuous modulation of electronic structure of stable thiolate-protected Au25 cluster by Ag doping.
The effect of Ag doping on the electronic structure of a stable thiolate-protected Au(25) cluster (Au(25)(SR)(18)) was studied by measuring the optical spectra of Au(25-n)Ag(n)(SC(12)H(25))(18) (n = 0-11) and the results reveal that the electronic structure of Au(25)(SC(12)H(25))(18) is sensitive to Ag doping and is continuously modulated by incorporation of Ag atoms.

متن کاملControlled reduction for size selective synthesis of thiolate-protected gold nanoclusters Aun(n = 20, 24, 39, 40)
This work presents a controlled reduction method for the selective synthesis of different sized gold nanoclusters protected by thiolate (SR = SC2H4Ph). Starting with Au(III) salt, all the syntheses of Aun(SR)m nanoclusters with (n, m) = (20, 16), (24, 20), (39, 29), and (40, 30) necessitate experimental conditions of slow stirring and slow reduction of Au(I) intermediate species. By controlling...
