“…Such situation is presented in Figs. 2a, b and c. The narrowing of the lines during the cooling of the sample down is characteristic of the localization of the electrons on the C60 molecule [5,10]. If we left the sample for a relatively long time (52 h) at room temperature the signal due to C radicals dominates over that from C and g-values are g 3 -= 2.0013 and g1-x = 1.9998, respectively (Fig.…”

“…A comparison of such results with the data obtained from EPR studies of electrochemically produced C60 radicals with different valences (υ) in solution [6][7][8] would permit verification of the EPR signals due to ion radicals of speciflc valence which are known to occur in pure C60 or in Me x C60 admixtured with alkali metals [2,9,10]. Therefore we could ascribe the following g-factor values: g+ .^.s 2.0025, g1-1.9998, g3-2.0014 to the C 6 0, CL and C ion radicals, respectively.…”

EPR and ΜΜMΑ studies of C60 upon K-doping have been performed. Two different and welł separated EPR narrow lines were detected for C1-60 and C at temperatures below 100 K. Time dependent changes in the intensities of both CL and C3-60 lines were observed when the system undergoes an eutectoid transformation. The evolution of superconductivity with two T' related to dicherent valences (v) of C6Ó ion radicals have been found.

The domain structure of new nanocomposites has been investigated by Fourier transform infrared spectroscopy, wide-angle X-ray scattering, and differential scanning calorimetry techniques. Solid-state 1 H NMR techniques were used to study molecular dynamics and domain sizes in new nanocomposites. Information about the electronic properties of these nanocomposites was obtained by means of electron paramagnetic resonance method. It was shown that the structure and molecular dynamics of new nanocomposites were strongly dependent on the properties and concentration of fullerene derivates. V C 2014 AIP Publishing LLC.

“…The ''dark'' signals are present even in starting fullerenes and may be attributed to defects due to the interaction of fullerenes with oxygen [37,38]. The intensity of these signals is 0.01-0.1% of the mass of the sample and strongly depends on methods of the fullerene preparation and storage.…”

Light-induced ESR (LESR) spectroscopy was used to study photoinduced electron transfer (PIET) in the crystals of the C 60 donor=acceptor complexes. High-field LESR signals attributed to C À 60 (g ¼ 1.9984 À 1.9992 and DH ¼ 3 À 6 G at 100 K) were observed in fullerene complexes with Leuco Crystal Violet (LCVÁC 60 ÁC 6 H 5 Cl, 1), N,N,N 0 ,N 0 -tetramethyl-p-phenylenediamine (TMPDAÁC 60 , 2), and bianthrone ((BA) 2 C 60 , 3), whereas a low-field LESR signal in 2 was attributed to TMPDA . þ . Microwave power studies reveal two independent spins in 2 and show high relaxation rates for photoinduced spins on C À 60 . The LESR signals consist of a major long-lived ''persistent'' component and a minor ''prompt'' one, which disappears immediately after light is off. The maximal intensity of the LESR signals was observed for the excitation of 1-3 below 2 eV. This range of photon energy corresponds to direct intermolecular charge transfer from donor to C 60 molecules. PIET is temperature activated with E a ¼ 23, 43 and 49 meV for 1, 2, and 3, respectively. Photoinduced spin susceptibility attains the maximum at 30 K in 1 and decreases with temperature down to 4 K indicating a possible The 3=[315]antiferromagnetic interaction of spins, while in 2 it increases with the temperature decrease down to 4 K.
