Ligand Effect on Gold Nanomolecules Demonstrated Using Aliphatic, Aromatic and Bulky Thiolate Ligands
Atomically precise thiolate protected gold nanoparticles (AuNPs) known as gold nanomolecules (AuNMs) are intensely pursued owing to their feasibility to elucidate their structure by single crystal X-ray crystallography. They have distinct number of Au atoms (n) and thiolate (-SR, R-hydrocarbon …

The detection of nitric oxide and its reactivity with transition metal thiolate complexes
… redox active units, such as transition metals or thiolate ligands. To gain insight into how NO might regulate biological processes by interacting with these redox active species, we have initiated a fundamental study of the reactivity of NO with transition metal thiolate model complexes. Our …

Structural Analysis Of Bulky Thiolate-Protected Gold Nanomolecules
Routine preparation of thiolate-protected gold nanomolecules involves, most commonly, straight-chain organic thiolate ligands for which the sulfhydryl `head' group is bound to a primary carbon atom. The primary connectivity of these sulfur atoms, such as for the case of n-hexanethiol and …

Gold Nanomolecules : Developing Synthetic Protocols, Characterization And Investigation Of Ligand Effects On Structure And Properties
… atmospheric conditions and most chemicals. Gold thiolate nanomolecules, which is the primary focus of this dissertation research, are chemical molecules with a fixed number of gold atoms and organo-thiolate ligands. They are of the form Aux(SR)y and possess molecule-like properties as a result of …
