Thermodynamic Study of the Reactivity of the Two Topological Point Defects Present in Mixed Self-Assembled Monolayers on Gold Nanoparticles

Devries, Gretchen A.Talley, Frajovon R.Carney, Randy P.Stellacci, Francesco2011-06-062011-06-062011-06-06200810.1002/adma.200702472https://infoscience.epfl.ch/handle/20.500.14299/68433When a mixed self-assembled monolayer forms on the curved surface of a gold nanoparticle two opposed point defects must form for topological reasons. Here we present a thermodynamic study proving that these defects are more reactive than other sites on the nanoparticle, and demonstrate that the energy of the reaction depends on the ligand molecules.SCANNING-TUNNELING-MICROSCOPYPROTECTED METAL NANOPARTICLESPHASE-SEPARATIONCLUSTER MOLECULESORGANIC-SURFACESBUILDING-BLOCKSDYNAMICSAU(111)ALKANETHIOLSSTABILITYThermodynamic Study of the Reactivity of the Two Topological Point Defects Present in Mixed Self-Assembled Monolayers on Gold Nanoparticlestext::journal::journal article::research article
