摘　　要：Introduction Although devices based on pseudorotaxanes, cantenanes, and rotaxanes are commercialized yet, several researches have been done on the applications of these donor-acceptor molecules. A promising area is the field of nanotechnology. The miniaturization of semi-conductor technology by the ＂top-down＂ approach is limited by the wavelength of the radiation used in the lithography to prepare electronic components. Therefore, the ＂bottom-up＂ may be more suitable to create devices with sizes down to the molecular level. A molecular or supramolecular system, in which the relative position of the component parts can be altered by an external stimulus, a molecular switch, can act as the basic unit for the creation of new molecular devices .Introduction Although devices based on pseudorotaxanes, cantenanes, and rotaxanes are commercialized yet, several researches have been done on the applications of these donor-acceptor molecules.
