“…In fact, it reacts with a number of different types of radicals and normally it undergoes multiple addition reactions, leading to adducts with different stability. [72][73][74][75] When they were irradiated in molecularly dispersed forms, the behavior of fullerenes was investigated by Cataldo et al 76 In presence of air the interference of oxygen is evident and the radiolysis should be conducted in high vacuum to avoid the interference of oxygen. A detailed analysis of the kinetics of the multiple additions of benzyl radicals to the fullerene cage was made spectrophotometrically with the determination of the addition rate constants at the each addition step and the average number of benzyl groups added to the fullerene cage as function of the radiation dose.…”

“…В работе [20] рассмотрены процессы олигомеризации фуллеренов С 60 и С 70 под влиянием совокупности поражающих факторов, а в [21] рассмотрены процессы радиолиза фуллерена. При этом показана возможность присоединения к фуллерену бензильных групп, а также окисления под действием облучения в присутствии кислорода.…”

Porphyrins and their fullerene complexes are promising materials for organic photovoltaic structures. However, the stability of the properties of organic components under hard radiation is poorly studied. Here, the influence of γ irradiation with medium (about 10^4 Gy) and large (10^7 Gy) doses on the photoluminescence of thin structurally perfect films of both pure porphyrin ZnTPP and ZnTPP/C_60 composite films in the molar ratio of 1.3: 1 is investigated. It is shown that the intensity of the electronic radiative transition (626 nm) decreases under the effect of γ irradiation, and the dose dependence is threshold. The threshold dose is ~20 kGy for the ZnTPP films. The intensity of the electron-vibrational part of the spectral dependence of the PL (670–690 nm) for both types of samples decreased at initial irradiation doses and decreases less with a further increase in the irradiation dose than for the purely electron transition. The addition of a fullerene in nanocomposite films increases the threshold dose, after which the PL of the films started to degrade, by a factor of ~2.5. Herewith, the spectral components of the PL associated with the manifestation of the radiation transition of the fullerene C_60 are more stable under γ irradiation.
