We found [60]fullerene (C60) to be soluble in polar solvents such as acetonitrile and acetone in the presence of syndiotactic poly(methyl methacrylate) (st-PMMA). The solubility of C60 in acetonitrile drastically increased from 0.00 to 0.27 mg/mL upon the addition of st-PMMA at the polymer concentration of 4 mg/mL. Furthermore, the solubility increased with the concentration of st-PMMA. Transparent st-PMMA films containing C60 were prepared by casting an acetonitrile solution of C60 with st-PMMA. X-ray diffraction analysis of the films revealed the formation of st-PMMA/C60 inclusion complex in which the C60 molecules were encapsulated within a helical st-PMMA cavity.
