摘要：

Self-assembled monolayers (SAMs) with terminal hydrogen bonding groups can have remarkably different structure and dynamics to those of the more familiar alkenethiol SAMs. The effect of carboxylic acid terminal groups on the structure and dynamics of gold nanoparticle SAMs is investigated by C-13 NMR, 2D WISE NMR, and FTIR spectroscopies. A markedly increased conformational order is reported, compared to that of methyl-and hydroxy-terminated SAMs, along with a strong thermal hysteresis of the chain order, speculated to be due to a change from intra-to interparticle hydrogen bonding.
