The mechanochemical reaction of C60 and Bi(NO3)3·5H2O

The mechanochemical reaction of C60 and Bi(NO3)3·5H2O was performed under ball-milling condition. The product was well characterized by spectroscopic methods such as IR, Raman, UV-vis, 13C NMR, as well as elemental analysis method. The spectroscopic investigation indicates that some hydroxyl and nitro groups are attached to the C60 and no profound structural changes occur for the C60 cage in the product. The elemental analysis gives an average composition of C60(NO2)2(OH)21 for the product. A possible mechanism is suggested for the reaction.
