FIELD: chemistry.
SUBSTANCE: invention relates to 1',2',5'-trisubstituted fulleropyrrolidines of formula (1), where C2n is the carbon skeleton of fullerene C60, in which R and R' are the same or mutually different and represent a substituent in the form of a C1-C8 alkyl group with a normal or branched structure, R1 is hydrogen, R2 represents a substituent in the form of a C1-C8 alkoxy group with a normal or branched structure, -O-(CH2)2-O-(CH2)2-CH3 group, while n and m represent the number of substituents R1 and R2 in the corresponding phenyl rings which are attached to the pyrrolidine moiety and are an integer from 1 to 3, a method for the preparation of fulleropyrrolidines of formula (1) and their use in photovoltaic cells, preferably in organic solar cells with volumetric heterojunction and photodetectors to improve open-circuit voltage and energy conversion efficiency in solar cells.
.
EFFECT: in the invention 1',2',5'-trisubstituted fulleropyrrolidines, a method for their preparation and use in a photovoltaic cell are proposed.
