FIELD: chemistry.

SUBSTANCE: invention relates to sulphur-containing fullerene derivatives of general formula , where X denotes a negative charge (-) which is localised on the fullerene backbone, or a hydrogen atom (H) or a chlorine atom (Cl), where in general formula 1, the fragment S-R¹ is defined as a residue of thio acid or ester thereof, which is bound to the fullerene backbone through a sulphur atom as shown graphically in formula 1, and R¹ has the formula XCOOR; X is a linear or branched alkylene (C_nH_2n; n=1-20) radical; R is a hydrogen atom (H), a linear or branched alkyl (C_nH_2n+1; n=1-20), an alkenyl (C_nH_2n-1 n=1-20) or alkynyl radical (C_nH_2n-3; n=1-20); is a residue of an amide of thio acid which is bound to the fullerene backbone through a sulphur atom as shown graphically in formula 1, where R¹ has the formula XCONRR'; X is a linear or branched alkylene (C_nH_2n; n=1-20) radical; R and R' are hydrogen atoms or linear or branched alkyl (C_nH_2n+1; n=1-20) radicals; a thiol residue, where R¹ is a hydrogen atom or a linear or branched alkyl (C_nH_2n+1 n=1-20) radical or a saturated (C_nH_2n-2; n=3-8) ring; a fragment of general formula -S(CH₂)_nSR, bound to the fullerene backbone thorugh a sulphur atom as shown graphically in formula 1, where R is a hydrogen atom or a linear or branched alkyl (C_nH_2n+1; n=1-20), alkenyl (C_nH_2n-1; n=1-20) or alkynyl radical (C_nH_2n-3; n=1-20), as well as a saturated (C_nH_2n-2; n=3-8), unsaturated (C_nH_2n-4; n=5-8, C_nH_2n-6; n=5-8, C_nH_2n-8; n=8) or an aromatic ring; a fragment of general formula -S(CH₂)_nNRR or -S(CH₂)_nN⁺RR'R"X", which is bound to the fullerene backbone through a sulphur atom as shown graphically in formula 1, where R, R and R" are hydrogen atoms or linear or branched alkyl (C_nH_2n+1 n=1-20) radicals; as well as saturated (C_nH_2n-2; n=3-8) rings; X" is any anion. The invention also relates to a method of producing said compounds.

EFFECT: novel compounds are obtained, which can be used in biomedical research and in pharmacology, as well as in organic photovoltaics.
