Expanding The Scope Of Clickable Azide-Functionalized Nanoclusters To Include Au144, Johanna A. De Jong
Electronic Thesis and Dissertation Repository
Thiolate-protected Au144 nanoclusters (NCs) are an intriguing member of the gold NC family. Their geometric structure, distinct electrochemical features, and susceptibility to structural rearrangement under the duress of ligand exchange have been studied. However, there are currently no established protocols for surface modification or tuning of their ligand shells post synthesis. Here, the direct synthesis of three regioisomers of azide-modified Au144 NCs with 60 azide moieties, i.e., Au144(SC2H4C6H4-N3)60, is reported, in which the azide functionality is located at the ortho-, meta-, or …
