[60]-Fullerene and its four ortho-quinodimethane adducts, one of them in oligomeric form, were reduced by three different methods : (a) by cathodic reduction, (b) in photoexcited TiO2 suspension, and (c) quenching photoexcited fullerene by triethylamine donor. The radicals obtained were mainly investigated by EPR and also characterized by vis-near-IR measurements. All three methods of generation gave two identical radical products : the primary radical A, which is a fullerene mono-anion, with EPR spectral parameters g(A) = 2.0000 and peak-to-peak width pp(A) = 0.09 mT for [60]-fullerene, pp(A) = 0.105 for its adducts and pp(A) = 0.19 mT for the fullerene oligomer. The near-IR band of A at 1077 nm for [60]-fullerene shifted into the region of 1010nm for its ortho-quinodimethane adducts. As a consecutive product of A, radical B was found with g(B) = 2.0006 and pp(B) = 0.07 mT for all [60]-fullerene adducts. The EPR signal of B converts to A after stopping photogeneration, resulting in a total increase of the spin susceptibility in the form of fullerene mono-anion A. The formation of fullerene di-anion or fullerene associates is considered as an alternative.
