Au40(SR)24 cluster as a chiral dimer of 8-electron superatoms: structure and optical properties.

Abstract

We predict and analyze density-functional theory (DFT)-based structures for the recently isolated Au(40)(SR)(24) cluster. Combining structural information extracted from ligand-exchange reactions, circular dichroism and transmission electron microscopy leads us to propose two families of low-energy structures that have a chiral Au-S framework on the surface… (More)
