Proposed asymmetric synthesis approach
The addition of silver trifluoroacetate to a triphenylphosphine-protected CAuI6 cluster creates a chiral-at-carbon hexasilver(I)-alloyed tetragoldmethane (CAuI4AgI6) cluster through etching of two gold(I) atoms. Further, selective asymmetric synthesis can be achieved by utilizing homochiral carboxylate ligands.

Release Summary

The development of atomic level molecular editing methods for metal clusters is an important avenue in synthetic chemistry that can expand the structure diversity and functionality of these compounds. In a new study, researchers have developed a novel, highly selective asymmetric synthesis approach to develop chiral optical metal clusters with photoluminescence. This approach can contribute to the development of chiral luminescent nanomaterials, benefiting several industries.
