Adding a compact dihydromethano (CH2) group to a 58 pi-indene fullerene (C-60(Ind)) creates a 56 pi-electron dihydromethano/indene fullerene (C-60(CH2)(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 CH2 addend.
