Electrochemical benzylation of [60]fullerene-fused lactones with different motifs unexpectedly affords three types of ring-opened benzylated adducts under different conditions. Both [60]fullerene-fused δ- and γ-lactones can be benzylated to generate ring-opened mono- and bis-benzylated adducts in good yields. In addition, representative fullerene products have been applied as efficient electron-transport materials in perovskite solar cells.
具有不同结构单元的[60]富勒烯稠合内酯的电化学苄基化反应在不同条件下意外地得到了三种类型的开环苄基化加合物。[60]富勒烯稠合的δ-和γ-内酯均可进行苄基化反应，以良好的产率生成开环的单苄基化和双苄基化加合物。此外，代表性的富勒烯产物已被用作钙钛矿太阳能电池中的高效电子传输材料。
