Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2003 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Gold clusters protected with self-assembled monolayers of sodium, 10-mercaptodecanesulfonate, HS(CH2)10SO 3Na, and 11-mercaptoundecanylphosphonic acid, HS(CH2) 11PO3H2, were synthesized to provide negatively charged nanoparticles. The negatively charged end groups of the sulfonate- and phosphonate-monolayers protected clusters, SO3-MPCs and PO 3-MPCs, allowed the particles to be water soluble in addition to be stable in air, and can be dried and redissolved without change. Modifications of experimental conditions, namely the thiol:gold ratio, gold concentration and the type of surfactant, yielded MPCs of 1.8--5.7 nm core diameters with a broad range of size dispersity, and solubilities. Transmission electron microscopy, proton nuclear magnetic resonance (1H NMR), UV-Visible and infrared spectroscopies, thermogravimetric and zeta-potential analyses were consistent with nanoparticle formation. The chain conformation, dynamic behavior and ordering of SO3-MPCs and PO3-MPCs were further investigated by solid-state NMR. Despite the high surface curvature of the nanoparticles and the bulky end groups, medium length chains of SO 3-MPCs (C10) and PO3-MPCs (C11) showed a high degree of organization and restricted mobility when compare to long chains of alkanethiolate MPCs (C18). The more extensive hydrogen bonding interactions between the phosphonic acid groups led to a reduced chain mobility and a higher thermal stability. The PO3-MPCs exhibit a high order-disorder transition, partial decomposition and a very marked hysteresis in the chain recrystallization similar to MPCs stabilized by HS(CH2)nCO2H. Solid-state 31P-NMR allowed studies of the hydrogen-bonded self-assembled structure in the PO3-MPCs as well as in the bulk phosphonic acid. The 1.8 nm-diameter SO3-MPCs produced large aggregates in presence of poly(diallyldimethyl-ammonium chloride) (PDADMAC). However, the encapsulation of individual particles was favored when the same polyelectrolyte" --
