Linking gold nanoparticles with conductive 1,4-phenylene diisocyanide-gold oligomers

Abstract

It is demonstrated that 1,4-phenylene diisocyanide (PDI)-gold oligomers can spontaneously bridge between gold nanoparticles on mica, thereby providing a strategy for electrically interconnecting nanoelectrodes. The barrier height of the bridging oligomer is 0.10 ± 0.02 eV, within the range of previous single-molecule measurements of PDI. © 2013 The Royal Society of Chemistry.
