FIELD: chemistry.

SUBSTANCE: invention relates to organic synthesis and specifically to method of producing norbornene-substituted cyclopropane fullerene derivatives and synthesis of high-molecular compounds on its basis. Method for producing norbornene-substituted generally formulated cyclopropane fullerene derivatives (9) by reacting the fullerene C₆₀ with complex ester of Formula 8, taken in the molar ratio between fullerene C₆₀: ether = 1: 1, in the presence of solvent and base at temperature 20-25 °C for 0.5-1.0 hours. Invention also relates to a method of producing polymers by polymerising norbornene-substituted cyclopropane fullerene derivatives of general formula (9) in the presence of I-generation Grubb's catalyst of general formula (10), taken in molar ratio of Fullerene derivative: Grubb's catalyst I = 35:1, in atmosphere of argon and in organic solvent at temperature 20-25 °C during 12 hours, adding to the reaction mixture of ethyl vinyl ether for removal of catalyst residues, precipitation of polymer in methanol.

EFFECT: method enables to obtain norbornene-substituted cyclopropane fullerene derivatives, capable for metathesis polymerisation with formation of Fullerene containing polymers, followed by formation of thin films, serving as acceptor components in photovoltaic devices.
