ELECTRICAL-TRANSPORT IN MONOLAYERS OF PHTHALOCYANINE MOLECULAR WIRES AND AFM IMAGING OF A SINGLE WIRE BRIDGING 2 ELECTRODES

We report on several steps that are of interest for electrical transpo rt studies on single molecular wires. Current-voltage measurements on monolayers of phthalocyaninepolysiloxane wires as a function of temper ature are consistent with the space-charge-limited-current model. Isol ated wires are firmly immobilized on a substrate corrugated with metal electrodes by embedding them in a Langmuir-Blodgett monolayer of cell ulose. High-resolution atomic-force-microscopy images have been obtain ed of a single molecular wire bridging two closely spaced electrodes.
