Activation of Thiols at a Silver Nanoparticle Surface

Abstract

Reactions of thiols that are used to modify nanoparticle (NP) properties at the surface of noble-metal NPs involve an activation process. By detecting second harmonic generation from the Ag NP surface, the activation energy Ea for the adsorption of 1,2-benzenedithiol onto silver nanoparticles in colloids was determined to be 8.4 kcal mol−1 (see picture), which may arise from the transition state (T.S.) in the bonding reaction.
