Abstract: An unexpected, divergent and efficient approach toward furanoid-bridged fullerene dimers C <subscript>120</subscript> O and C <subscript>120</subscript> O <subscript>2</subscript> was established under different solvent-free ball-milling conditions by simply using pristine C <subscript>60</subscript> as the starting material, water as the oxygen source and FeCl <subscript>3</subscript> as the mediator. The structures of C <subscript>120</subscript> O and C <subscript>120</subscript> O <subscript>2</subscript> were unambiguously established by single-crystal X-ray crystallography. A plausible reaction mechanism is proposed on the basis of control experiments. Furthermore, C <subscript>120</subscript> O <subscript>2</subscript> has been applied in organic solar cells as the third component and exhibits good performance.<br />Competing Interests: There are no conflicts to declare.<br /> (This journal is © The Royal Society of Chemistry.)
