Advanced ~13C Nuclear Magntic Resonance Investigation of Metal-Ligand Interactions in Monolayer-Protected Gold Nanoparticles:NMR Shifts and Relaxations

摘要

While self-asembled monolayer (SAM) systems have been intensively investigated since the seminal work of Nuzzo and others in the later 1980s,the detailed nature of the interactions between thiol and gold in terms of surface bonding and ligand motion,a central theme crucial for any further advancements in the field of SAMs,is still eusive and subject to controversy.
