An efficient triflic anhydride-mediated synthesis of [60]fullerene (C 60 )-fused dihydrophenalenones from C 60 and 1-naphthoic acids has been developed, representing the first one-step construction of C 60 -fused polyaromatic ketones under metal-free conditions. In addition, the C 60 -fused dihydrophenalenones can be reduced to C 60 -fused dihydrophenalenes and C 60 -fused dihydrophenalenols. The structures of the products were unambiguously established by single-crystal X-ray diffraction. A possible reaction mechanism is proposed based on control experiments. Furthermore, a representative C 60 -fused dihydrophenalenone was employed as a third component in organic solar cells, leading to improved device performance.
