A three-component synthesis of 60fullerene-fused tetrahydropyridines was developed via the reaction of 60fullerene with chalcones in the presence of magnesium nitride as the nitrogen source under ball-milling conditions. This method utilizes easily available starting materials, eliminates the need for metal catalysts and ligands, and delivers the products under mild conditions. Furthermore, one of the synthesized products was successfully employed as an interlayer in perovskite solar cells to increase the power conversion efficiency.
