    • 13C NMR experiments. Minor peaks can be observed up to 45-50 min; we assigned them as belonging to fullerene trimers. The dimer 2 elutes on a Cosmosil 5PBB column (10 × 250 + 10 × 20 mm guard 5PBB column) at 28.2 min with toluene at 7.5 mL/min, at 16.1 min with 3 mL/min of chlorobenzene, and at 12.1 min with 2.5 mL/min of ODCB.

    • note
    • To determine purity, we used recycling HPLC analysis. Elemental analysis is not suitable for some fullerene derivatives because of the poor combustion which systematically gives a lower content of carbon. Moreover, the hydrogen content of the fullerene dimer 2 (theor. 0.27%) is even smaller than the usual error limit for combustion analysis.

    • The values discussed in the text for MALDI TOF MS of 2 refer to an experiment made in linear mode, negative ionization using dithranol as matrix (20 kV accelerating voltage, 70% grid voltage, 125 averaged scans).

    • 13C NMR experiments since the sample had low solubility. Four other resonances were identified as belonging to impurities in the sample: 0.25 and 30.2, 54.1, and 68.1 ppm.
