Outline of Final Research Achievements

Insulated conductive molecules, in which the conjugated compounds are covered by a cyclic protective sheath, have attracted considerable attention because of their potential applicability in next-generation molecular electronic devices. We have developed new methods of synthesizing insulated conjugated molecules involving the self-inclusion of rotaxane precursors linking conjugated units as a guest and permethylated cyclodextrin (PM CD) as a macrocyclic host. A new method for synthesizing insulated molecular wire (IMW) through the polymerization of insulated conjugated molecules as monomers was also developed. The obtained IMWs are highly soluble in organic solvents and have a high covering ratio, rigidity, and photoluminescence efficiency; further, they show high charge mobility, even in the solid state. We also developed a new type of molecular wiring method based on the polymerization or co-polymerization of an insulated conjugated monomer between nanosized electrodes.
