In this study, basic Au-25(4-PyET)(18) clusters were successfully transformed into cationized Au-25(4-PyET-CH3+)(x)(4-PyET)(18-x) clusters without altering their core structure through a Menshutkin S(N)2 reaction. This method not only offers a simple cationization approach, but also provides a protocol for modifying the surface functionalities of molecular metal clusters via synthetic reactions.
Surface chemical reactions on atomically precise metal clusters have considerable attention for opening a new platform for cluster functionalization. In this study, basic Au-25(4-PyET)(18) (4-PyET = -SCH2CH2Py; Py = pyridyl) clusters were successfully transformed into cationized Au-25(4-PyET-CH3+)(x)(4-PyET)(18-x) clusters, without altering their Au-25 cores, through the Menshutkin S(N)2 reaction of their surface Py moieties. This study offers not only a simple cationization method but also a protocol for modifying the surface functionalities of molecular metal clusters via a synthetic reaction.
