In this work, some novel methanofullerene derivatives of the formula [6, 6]-phenyl-C61-(CH2)n-COOR, where n=2, R=C4H9, C3H7, C2H5, CH3, CH2C6H5, CH(CH3)2, have been studied together with the reference compound PCBM (n=3 and R=CH3). We have measured the dependence of polymer photoluminescence (PL) in the blends of poly(2-methoxy-5-(3'7'-dimethyloctyloxy)-1,4-phenylene-vinylene) (MDMO-PPV) and new fullerene derivatives, as well as PCBM and C60, on the concentration of fullerene. Strong PL quenching due to the photoinduced electron transfer was observed for all fullerenes studied. The derivatives with R=C4H9, C3H7, and C2H5 showed a more effective quenching than PCBM and C60. This means that the novel metanofullerens may be selected as good acceptor materials for organic photovoltaic cells.
