Supplementary material from "Highly efficient synthesis of [60]fullerene oxides by plasma jet"

Atmospheric pressure nonequilibrium plasma jet has been applied to the synthesis of [60]fullerene oxides (C₆₀O_n) for the first time. C₆₀O and C₆₀O₂ were produced and isolated in high yields up to 44% and 21%, respectively. The structural assignment of C₆₀O was confirmed by comparison with the reported spectroscopic data. Theoretical calculations of ¹³C NMR chemical shifts for eight isomers of C₆₀O₂ were performed and compared with the experimental data to assign the most possible structure for the obtained C₆₀O₂ dominantly as an e isomer.
