- 中文摘要: A unique reorganization process, which was induced by HCl treatment of the self-assembled monolayers of n-alkanoic acids on silver surfaces, was visualized by polarized reflection absorption IR spectroscopy. The process can be reversible or irreversible, depending on the chain length of the monolayer-forming acid. Thus for C16 acid, the highly oriented and crystalline monolayer packing phase reorganized reversibly into isotropic microcrystallites. For C8 acid, the ordered packing phase reorganized irreversibly into a disordered, liquid-like phase. For C24 acid, reversible change in orientation occurred. All changes are due to the protonation-deprotonation reaction occurring at the binding head group.
