A Dynamic View of Self-Assembled Monolayers

The dynamics of chains in self-assembled monolayers of alkylthiols on gold colloids (RSH/Au) and long-chain organic acids (RCO2H, RPO3H2) on metal oxides (ZrO2, TiO2, Al2O3) have been probed using solid-state NMR techniques. The dynamic features which we have observed are closely associated with surface-tethered chains and not with the substrate nor the chemistry of the headgroup. The influence of polar functional groups on these properties will also be discussed.
