Wires
The sole purpose of molecular wires is to electrically connect different parts of a molecular electrical circuit. As the assembly of these and their connection to a macroscopic circuit is still not mastered, the focus of research in single molecule electronics is primarily on the functionalized molecules: molecular wires are characterized by containing no functional groups and are hence composed of plain repetitions of a conjugated building block. Among these are the carbon nanotubes that are quite large compared to the other suggestions but have shown very promising electrical properties.
The main problem with the molecular wires is to obtain good electrical contact with the electrodes so that the electrons can move freely in and out of the wire.

Famous quotes containing the word wires:
“Putting people in a room and strapping wires to their wrist to find out if I make them tingle when I’m telling them about Beirut is a long way from Edward R. Murrow.”
—Linda Ellerbee (b. 1932)
“Under a world of whistles, wires and steam
Caboose-like they go ruminating through
Ohio, Indiana—blind baggage—
To Cheyenne tagging . . . Maybe Kalamazoo. See Vagagonds”
—Hart Crane (1899–1932)
“The symmetrical piles of white bodies,
the round white breast-shapes of the heaps,
the smell of the smoke, the dogs the wires the
rope the hunger. It had happened to others.
There was a word for us. I was: a Jew.”
—Sharon Olds (b. 1942)
