FIELD: organic chemistry, chemical technology.

SUBSTANCE: invention relates to novel derivatives of fullerenes comprising organic amines and hydrogen atoms bound to fullerene-C₆₀ molecule by 6,6-double bonds of the general formula: C₆₀H_n(R₁R₂N)_n wherein R₁ means -C₆H₅CH₂; R₂ means -C₆H₅CH₂; n = 4 (tetra-(dibenzylaminohydro)[60]fullerene); R₁ means -C₅H₉; R₂ means hydrogen atom (H); n = 3 (tri-(cyclopentylaminohydro)[60]fullerene). Also, invention relates to using derivatives of fullerenes, in particular, (tetra-(benzylaminohydro)[60]fullerene, (tetra-(dibenzylaminohydro)[60]fullerene, tri-(cyclopentylaminohydro)[60]fullerene, 2-(azahomo[60]fullereno)-5-nitropyrimidine, 1,3-dipropyl-5-[5'-(azahomo[60]fullereno)pentyl]-1,3,5-triazin-2,4,6(1H,3H,5H)-trione, O,O-dibutyl-(azahomo[60]fullereno)phosphate as acceptors of electrons in composites polymer/fullerene designated for photovoltaic cells. Also, invention relates to photovoltaic device comprising mixture of poly-conjugated polymer and abovementioned fullerene derivative or their mixture as an active layer. Also, invention relates to a method for synthesis of derivatives of fullerenes comprising aromatic amines and hydrogen atoms bound to fullerene-C₆₀ molecule by 6,6-double bonds. Method involves interaction of C₆₀ with the corresponding organic amine in solution, and this reaction is carried out in aromatic solvent medium in amine excess at temperature 25-70°C for 2-5 days followed by evaporation of solution and precipitation of the end product by addition of alcohol.

EFFECT: improved method of synthesis.
