We used the well - characterized malonato [ 60 ] fullerene diester monoadduct C60 [ > M ( t - Bu ) 2 ] as the starting fullerene derivative to provide a better synthetic route to C60 [ > M ( C3N6 ( + ) C3 ) 2 ] via transesterification reaction under trifluoroacetic acid catalyzed conditions .
 Chemical: malonato [ 60 ] fullerene diester; Chemical: C60 [ > M ( t - Bu ) 2 ]; Chemical: fullerene; Chemical: C60 [ > M ( C3N6 ( + ) C3 ) 2 ]; Chemical: trifluoroacetic acid
