Molecular electronics is a relatively new and fascinating area of research. However, as most single organic molecules are not conductive in a classical sense, long-range electronic transport through single molecules is unlikely to be useful for practical electronic circuits. Our group is interested in composites of conductive nano-materials with functional organic molecules as attractive bases for molecular electronics. Structures such as carbon nanotubes and metal nanoparticles incorporating functional organic molecules have been shown to be possible candidates. We have prepared two dimensional, one dimensional Au nano-particle assemblies using organic molecules, and carbon nanotube / organic molecule composites. Their electric properties were studied using nanogap electrodes and PCI-AFM.
