AbstractIt is accepted that the monolayer ligand shell in monolayer-protected gold nanoclusters (MPCs) plays an important role in stabilizing the metal core structure. Previous reports have shown that the core and shell do not interact chemically, and very few studies investigating the intramolecular charge transfer (ICT) between the core and ligand shell in clusters have been reported. The underlying excited state relaxation mechanisms about the influence of solvents, the optically excited vibration, and the roles of the core and shell in charge transfer remain unknown to a large extent. Here we report a femtosecond transient absorption study of a Au-20(SR)(16) (R = CH2CH2Ph) cluster in toluene and tetrahydrofuran. The ICT from the outside shell to the inside core upon excitation in Au-20(SR)(16) is identified. The observed solvation-dependent oscillations in different solvents further confirm the photoinduced ICT formation in Au-20(SR)(16). The results provide a fundamental understanding of the structure-property relationships about the solvation-dependent core shell interaction in Au MPCs.
