| Outline of Final Research Achievements |
A reliable method of the molecular wiring between nanodot electrodes by using the polymerization as an ultimate bottom-up nanofabrication approach was proposed. First, a seed of the polymer, called initiator here, on the one electrode, from which the π-conjugated polymers grow. Second, the terminator is adhered on the other electrode. Both the lift-off from the initiator and touch down to the terminator could be expected in some probability and the resulting bridged π-conjugated polymers work as molecular wires. Concretely, surface-initiated and terminated chain growth condensation polymerization of 4-chloropyridine to yield poly(1,4-pyridinium) as molecular wire were investigated. Such enhanced basicity of the specially designed initiator and terminator control the polymerization in the chain growth manner. The chemical instability of the poly(1,4-pyridinium) due to electron deficient electronic structure should be improved for demonstration of the proposed molecular wiring.
