Preparation and characterization of gold nano-particles chemisorbed by pi-radical thiols
pi-Radical thiol-derivatized gold nano-particles with the average diameter of 4.1 nm were isolated, and about one hundred pi-radical ligands were found to be chemisorbed on the nanoparticle. The solid sample of the nano-particles showed an extremely broadened ESR signal with the peak-to-peak derivative line width (DeltaH(pp)) of 30 mT at 300 K.
