A series of unreported fullerodihydropyridine-3-ones were synthesized as a new family of fullerene derivatives in moderate to good yields by a simple one-step reaction of[60]fullerene with cheap and readily available β-substituted ethylamines in the absence or presence of arylacetaldehydes under the assistance of Cu(OAc)_(2).The in situ generation of arylacetaldehydes by the C—N bond cleavage of arylethylamines avoided their complex synthesis in advance and realized the preparation of fullerodihydropyridine-3-ones with structural and functional diversities,which may have promising applications in perovskite solar cells to improve the performance of photovoltaic devices due to the existence of a largeπ-conjugated system on the dihydropyridine-3-one ring.

It crystallizes in monoclinic, space group P2 1/c with a = 8.100（1）, b = 24.369（3）, c = 8.634（1） A, β = 105.380（2）°, V = 1643.1（4） A^3, Z = 4, Dc = 1.671 g/cm^3, F（000） = 856, μ（MoKa） = 0.273 mm^- 1, T = 294（2） K, the final R = 0.0400 and wR = 0.1021 for 2866 observed reflections with I 〉 2σ（I）. In this crystal there exist a number of H-bonds which link the molecules to form a three-dimensional infinite network structure. The thermal decomposition of the title compound was investigated by using TG-DTG and DSC techniques.
