Electrical transport in monolayers of phthalocyanine molecular wires and afm imaging of a single wire bridging two electrodes

We report on several steps that are of interest for electrical transport studies on single molecular wires. Current-voltage measurements on monolayers of phthalocyaninepolysiloxane wires as a function of temperature are consistent with the spacecharge-limited-current model. Isolated wires are firmly immobilized on a substrate corrugated with metal electrodes by embedding them in a Langmuir-Blodgett monolayer of cellulose. High-resolution atomic-force-microscopy images have been obtained of a single molecular wire bridging two closely spaced electrodes.
