Intra-Monolayer Hydrogen-Bonding in Monolayer Protected Gold Clusters

Abstract

Unlike the highly ordered Self-Assembled Monolayers (SAMs) formed on flat gold surfaces those on gold nanoparticles radiate from a roughly spherical center and are amorphous in structure. One result of this structural motif is that the strength of intra-monolayer non-covalent interactions, such as pi-stacking and hydrogen bonding, are a function of the distance of the recognition element from the colloidal core. We present here an exploration of these phenomena in amide functionalized thiols in MPCs where the amide functionality position was varied in the alkane chain.
