摘要：

The photoinduced electron transfer between conjugated polymers and a series of functionalized fullerenes was studied, A new photoluminescence signal was observed in the near IR (similar to 1,4 eV), This weak IR photoluminescence does not result from direct excitation of the fullerene, but from radiative electron-hole recombination between the fullerene excited state and the polymer ground state. The intensity of this recombination luminescence depends on the electrochemical nature of the functional group; it is observed only for fullerenes with first reduction potential higher than that of C-60.
