Conversion of Anionic [Au25(SCH2CH2Ph)18]− Cluster to Charge Neutral Cluster via Air Oxidation
Abstract
We report a solution-phase conversion process of the [Au 25 (SCH 2 CH 2 Ph) 18 ] − anionic cluster into a charge neutral cluster [Au 25 (SCH 2 CH 2 Ph) 18 ] 0 via air oxidation. The one-electron loss of the Au 25 − cluster and conversion to Au 25 0 is a surprise in light of the chemical inertness of gold nanoparticles. In contrast with the crystal structure of the anion cluster Au 25 −, which exhibits apparent structural distortions in the Au 25 S 18 framework, such distortions are not observed in the neutral cluster. The cluster charge effect is also manifested in the optical absorption spectra of the clusters. Given the only recently reported structure of the parent Au 25 − cluster, it is of substantial interest whether its one-electron oxidized product is similar to that of Au 25 − . This work unambiguously determined the structure of the one-electron oxidized product and correlates the structure with the optical properties.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
