Dynamics of photoexcited states of electron donor acceptor charge transfer complexes between C₆₀, C₇₀ and aromatic amines has been studied by picosecond transient gratings, picosecond pump to probe laser photolysis techniques in solution. The charge separation and spin dynamics of photoinduced paramagnetic centers have been studied by 2-mm and 3-cm EPR in single crystals of C₆₀ complexes with amines. The transitions between local excited states and the charge transfer state were analyzed by using electron transfer theory. The dynamics of photoexcited C₆₀, C₇₀ in liquid amine N,N-diethylaniline (DEA) and in mixtures of DEA with chlorobenzene was studied by picosecond transient gratings technique. The wavelength of excitation pulses was 528 nm, probe pulse 1055 nm. Two types of ion-radical pairs were found. The first type of pairs was the solvent separated pairs formed due to the quenching of singlet excited fullerenes by amine (low amine concentration). The second type of pairs was the contact ion pairs, which are the photoexcited donor acceptor complexes between fullerenes and amine (high amine concentration). Quenching rate constant is 1.4x10¹⁰ (Ms)^-1 The lifetimes of ion-pairs are 95 ps and 31 ps for solvent separated and contact pairs. Optical anisotropy of diffracted pulse decreases as the amine concentration increases. The amine concentration affects the initial anisotropy amplitude but not on the rate of the anisotropy decay. This effect was attributed to the donor acceptor complexes formation. The mechanism of the anisotropy lost for the charge transfer state is considered. The complete scheme of intersystem transitions between charge transfer state (contact ion- radical pairs) and local excited states in C₆₀,C₇₀/TPA complexes has been established. The dependence of rate constants of these transitions on solvent polarity were analyzed by using electron transfer theory. The agreement between experimental and theoretical dependence of triplet quantum yield of fullerene on solvent polarity could be obtained assuming the low frequency of promoting vibrations 500 cm^-1. The formation of ion-radicals in the single crystals of C₆₀/TPA and C₆₀/TMPD under visible illumination was studied. The quantum yield of long lived ion-radical states is about 10% in C₆₀/TPA crystals whereas in the C₆₀/TMPD the yield of ion-radicals is negligible small. 2-mm EPR spectra of photoinduced paramagnetic centers in C₆₀/TPA were obtained in the 80 - 300 K interval. Ion-radicals pairs spectra were found due to high spectral resolution of 2-mm EPR. Spin dynamics of these paramagnetic centers have been considered. Two PC with different relaxation and dynamics parameters are stabilized at irradiation of complex. C₆₀ molecules rotate activatively at low temperatures and the rate of this motion increases sharply at phase transition. This is accompanied with the change in the electron relaxation and in the paramagnetic susceptibility of the system. The change in the conformation of the complex cation also leads to the considerable increase in the rotation frequency. The data obtained show the evident advantages of 2-mm waveband EPR spectroscopy in the investigation of the fullerene complex. The method allows to analyze more completely and correctly the magnetic and relaxation parameters of paramagnetic centers of different mobility, to obtain fine peculiarities of molecular and spin dynamics in this complex. Undoubtedly, this method can be successfully used also in the investigation of other fullerene compounds.
