dc.description.abstract | Gold nanoparticles similar to 2 nm in diameter were synthesized with, oil average, between 0 and similar to 5.4 anionic thiols per particle. An electrochemical quartz-crystal microbalance Wits used to monitor the motion of ions and electrons during redox cycling (Charging) of thin films of these nanoparticles. When the electrochemistry was performed using a polyanion electrolyte too large to penetrate the nanoparticle film, the degree of oxidation that was possible was Found to be dictated by the average number of anionic ligands oil the particle Surface available for charge compensation. These anionic nanoparticle thin films were combined with previously reported/synthesized cationic nanoparticles into solution-processed nanoparticle film bilayers. We demonstrate using these bilayers that the control over charge compensation kinetics afforded by the use of a polyelectrolyte supporting electrolyte in conjunction with ionic surface functionalization allows for the selective charging of one layer of nanoparticles over the other and for the realization of structures consisting of oxidized and reduced nanoparticles in direct contact. | - |
