Isotopic exchange reactions reveal that all silver atoms in silver nanoclusters are exchangeable. This study provides atomic-level insights into metalloid cluster reactivity with homometal thiolates.
Area of Science:
- Nanomaterials Chemistry
- Surface Science
- Coordination Chemistry
Background:
- Understanding metalloid cluster-homometal thiolate interactions at the atomic level is limited.
- Homometallic exchange reactions offer a pathway to study intrinsic interactions without enthalpy changes from heterometal exchange.
Purpose of the Study:
- To investigate the atomic-level interaction between silver nanoclusters and homometal thiolates using isotopic exchange.
- To elucidate the mechanism of metal exchange within silver nanocluster structures.
Main Methods:
- Utilized isotopic exchange reactions with 107Ag and 109Ag isotopes.
- Employed electrospray ionization mass spectrometry (ESI-MS) and MS/MS to analyze cluster conversions.
- Studied the Ag44(SR)30 and Ag29(BDT)12(TPP)4 silver nanocluster systems.
Main Results:
- Demonstrated the complete exchangeability of all silver atoms within the Ag44(SR)30 nanocluster template.
- Identified the metal exchange in the Ag29(BDT)12(TPP)4 cluster as a shell-to-kernel transfer process.
- Provided atomic-level evidence of metalloid cluster reactivity in homometal thiolate environments.
Conclusions:
- Established a facile approach for investigating metalloid cluster-homometal thiolate interactions.
- Offered new insights into the dynamic nature and reactivity of silver nanoclusters.
- Results will guide the design and synthesis of future nanoclusters with tailored properties.
