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

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.
