An Advance Toward Ultra-

Portable Electronic Devices

Introduction

Scientists are reporting a key advance toward the long-awaited eraof "single-molecule electronics," when common electronic circuits incomputers, smart phones, audio players, and other devices mayshrink to the size of a grain of sand. The breakthrough is a methodfor creating and attaching the tiny wires that will connect molecularcomponents, reports a new study in the Journal of the AmericanChemical Society.

Molecular scale electronics Molecular scale electronics, also called

single molecule electronics, is a branch ofnanotechnology that uses single

molecules, or nanoscale collections ofsingle molecules, as electroniccomponents. Because single moleculesconstitute the smallest stable structures

imaginable this miniaturization is theultimate goal for shrinking electricalcircuits.

Single molecule electronics is an emerging field, andentire electronic circuits consisting exclusively ofmolecular sized compounds are still very far from beingrealized. However, the continuous demand for more

computing power together with the inherent limitations ofthe present day lithographic methods make the transitionseem unavoidable. Currently, the focus is on discoveringmolecules with interesting properties and on findingways to obtaining reliable and reproducible contacts

between the molecular components and the bulkmaterial of the electrodes.

as a molecular switch.:

One of the biggest problems with measuring on single molecules isto establish reproducible electrical contact with only one moleculeand doing so without shortcutting the electrodes. Because thecurrent photolithographic technology is unable to produce electrodegaps small enough to contact both ends of the molecules tested (inthe order of nanometers) alternative strategies are put into use.

Polymers for Use in Conductive Electronics toWitness Significant Growth:

The exceptional insulation capabilities of plastics havebeen pivotal to the use of polymers in the developmentof electrical and electronic devices. In addition toinsulation, the conductive properties of plastics

combined with superior design/processing methods areoffering economical solutions for the electrical/electronic(E/E) market. "Plastic electronics based on inherentlyconductive polymers (ICPs) and flexible substrates areset to change the face of the electronics industry," says

the analyst of this research service. "The global demandfor conductive electronic polymer products is forecast toexpand by 14.5 per cent per year until 2008."
