<p><P>PROBLEM TO BE SOLVED: To provide an organic n-type semiconductor material having improved solubility in an organic solvent and great linking ability to a p-type semiconductor. <P>SOLUTION: A C60 fullerene derivative represented by formula (I) includes a condensed ring, wherein R<SP>1</SP>is a perfluoroalkyl group, a perfluoroalkoxy group or perfluoropolyether group; and R<SP>2</SP>is a specific pyrrolidine ring having an alkyl-containing phenyl group at the second position. The C60 fullerene derivative is used for a charge transfer material, an n-type semiconductor material and an n-type semiconductor thin film and the like. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
