Abstract

A facile synthesis was employed to make a 56π-electron methano-PC 61BM with a very small 1,2-dihydromethano (CH2) group. This new fullerene derivative possesses high electron mobility (0.014 cm 2 V-1 s-1) and higher LUMO energy level (0.15 eV) than PC61BM. Bulk hetero-junction devices based on using poly(3-hexylthiophene) and methano-PC61BM as active layer exhibited better performance and thermal stability than those using the PC61BM analogue.
