Study of the optical and photovoltaic properties of N-methyl-1-(4-cytisinophenyl) fullerene-C60-[1,9] — pyrrolidine

In this paper new derivatives of fullerene C
₆₀
are synthesized. The structure of the molecule structure of the N-Methyl-1-(4-cytisinophenyl) fullerene-C
₆₀
-[1,9]-pyrrolidine was proved by NMR of
¹
H and
¹³
C spectroscopy. The spectral-luminescent properties of N-Methyl-1-(4-cytisinophenyl) fullerene-C
₆₀
-[1,9]-pyrrolidine were studied. It was established that the lifetimes of the excited states amounted to 0.31 ns and 0.6 ns, respectively. The photovoltaic properties of organic solar cells with a volumetric heterojunction based on fulleropyrrolidine were studied. It was shown that the use of fulleropyrrolidine as an acceptor was comparable to the VAC for the P3HT: PCBM system.
