    • This patent discloses a substituted fullerenes, compositions comprising the same, and their use as antioxidants. The substituted fullerenes comprise a fullerene core (Cn), wherein n is an even integer greater than or equal to 60, and (i) t —X3 groups bonded to the fullerene core, wherein: (i-a) t is an integer from 1 to 12, inclusive; and (i-b) each —X3 is inependently selected from wherein each R10 is independently >O, >C(R2)(R3), >CN+(R2)(R3)(R4), or >CHN+(R2)(R3)(R8), wherein R2, R3, and R4 are independently —H or —(CH2)d—CH3, wherein d is an integer from 0 to about 20, and each R8 is independently —(CH2)f—SO3−, —(CH2)f—PO4−, or —(CH2)f—COO−, wherein f is an integer from 1 to about 20; and (ii) u>O groups bonded to the fullerene core, wherein u is an integer from 0 to 12, inclusive
    • 该专利公开了一种取代的富勒烯,包含它们的组合物及其作为抗氧化剂的用途。 取代的富勒烯包含富勒烯核(Cn),其中n是大于或等于60的偶数整数,和(i)与富勒烯核键合的t -X 3+基团,其中:(ia )t为1〜12的整数,包括1和12; 和(ib)各自独立地选自其中每个R 10独立地为O,C(R 2)(R 2) (R 3)(R 3)(R 3)(R 3) (R 3)(R 8)和(CH 3)(R 3)(R 8)),或其中 R 2,R 3,R 4和R 4独立地是-H或 - (CH 2 CH 2) 其中d为0至约20的整数,并且每个R 8独立地为 - (CH 2)2 N - ) - (CH 2) - - - (CH 2)n - 或者 - (CH 2 - ) - - - - - - - - - - - - (CH 2) 其中f为1至约20的整数; 和(ii)键合到富勒烯核心的u> O基团,其中u是0至12的整数,包括0和12
