Dynamics of alkyl chains in monolayer protected metal clusters and their superlattices
Alkyl chains dynamics in monolayer protected metal cluster (MPC) systems of gold and silver have been studied by the quasielastic neutron scattering (QENS) technique. Isolated MPCs investigated are 6, 12 and 18 carbon n-alkyl chain thiolate protected 4 nm diameter gold clusters while the superlattices are their silver analogues. Evolution of dynamics with temperature is found to be very differe...
متن کاملRadical-induced Core Destruction of Monolayer-protected Metal Clusters
Chlorine radicals formed by the UV irradiation of solvents such as CCl 4 react with alkanethiolate-protected gold and silver clusters forming the corresponding metal salts and variously halogenated disul®des. Reaction rates depend on the chain length of the monolayer; whereas the reaction is over within tens of seconds for clusters protected with shorter chain monolayers, those with longer chai...
متن کاملAbsence of the rotator phase and evolution of dynamical motions in cluster monolayers
Alkyl chain dynamics in monolayer protected metal cluster systems has been studied by the quasielastic neutron scattering technique, using two different instruments having very different energy windows. Long chain thiolate protected clusters such as Au–ODT (Au–SC18H37) are rotationally frozen at room temperature ~RT! in a wide time scale of 10 to 10 s. The rotator phase is absent at RT even in ...
متن کاملDynamics of Alkyl Chains in Monolayer-Protected Au and Ag Clusters and Silver Thiolates: A Comprehensive Quasielastic Neutron Scattering Investigation
Temperature-dependent dynamics of monolayer-protected Au and Ag nanoclusters and silver thiolates have been investigated with quasielastic neutron scattering. The simplest motion in these systems is the uniaxial rotation of the chain, which evolves slowly with temperature. While longer chain monolayers (above C8) on Au clusters are rotationally frozen at room temperature, dynamic freedom exists...
