Adding a compact dihydromethano (CH 2 ) group to a 58π‐indene fullerene (C 60 (Ind)) creates a 56π‐electron dihydromethano/indene fullerene (C 60 (CH 2 )(Ind)) and raises the LUMO level with only a minimal increase in size. This class of compounds features reduced conjugation that raises the LUMO level, and a high electron mobility because of the small CH 2 addend.
