Recently, much attention has been paid to organic electronic devices such as organic solar cells, organic light emitting diodes, and organic transistors from the point of view of new energy resource, energy saving, low environmental impact, low cost process, and ubiquity. In such organic electronic devices, two kind of organic semiconducting materials are used. One is organic electron-donors as p-type materials. The other is organic electron-acceptors as n-type materials. Typical materials are fullerene and fullerene derivatives. However, development of acceptor materials is behind because functionalization of fullerene is rather difficult. If we push it up this part, we can accelerate the development of organic electronic devices. Functionalized fullerenes are obtained by chemical modifications of fullerenes. They have high electron affinity as fullerenes themselves. One can optimize photo-electronic function by the change of organic and inorganic moieties of functionalized fullerenes. In addition one can construct well-defined assembly structure of the functionalized fullerene molecules. Fullerene derivatives have high solubility giving good processability for fabrication of organic devices. We have investigated synthetic chemistry of fullerene derivatives, and conducted application studies to organic solar cells with newly designed fullerene derivatives, photocurrent generation devices which can switch the direction of photocurrent, fullerene-containing redox active liquid crystals, single molecular device motifs bearing two or three metal atoms on the fullerene core, metal-carbonaceous nano materials, and organic light emitting diode devices. We will discuss design of photo-electronic properties and well-defined supramolecular structures in such applications. . © nanoAC . . . . . . . . . .
