Abstract
Nanofibers of a fullerene derivative (phenyl-C61-butyric acid methyl ester, PCBM) and a conventional polymer (polyvinylpyrrolidone, PVP) composite were prepared by electrospinning of blended solutions in the mixed solvent of chlorobenzene and methanol. At a fixed concentration of PVP, the average diameter of fibers was found to decrease with increasing composition of PCBM, because of the increase of conductivity of spinning solutions. The increase in PCBM composition resulted in a relative blue shift in UV-vis absorption peak. PVP was easily removed from PCBM/PVP fibers by Soxhlet extraction. After the removal of PVP, pure PCBM were obtained as nanorods connected in fiber direction. The preliminary utilization of the PCBM nanostructure as an electron-acceptor material in polymer solar cells was investigated. ฉ 2013 The Authors.
