Air-stable n-channel organic transistors are fabricated using a newly synthesized soluble fullerene derivative. The air-stable nature of this molecule allows the realization of complementary circuits under ambient conditions without encapsulation. As shown in the figure, the I–V characteristics of the devices are retained even after exposure to air for a week. To the best of our knowledge, this is the first demonstration of an air-stable electron-transporting fullerene-based molecule.
