Was shown that laser energy in range 70 - 110 µJ/sm2 doesn't influence on formation (self-assembling) of C60 molecules in mass spectrometer ion source. The phenomenon of solvatochromism a month later after С60?NMP system preparation and also after system dilution by water was found by spectrophotometry. As a result of optical spectrum modeling was shown that the reason of slow solvatochromism is changing of electronic state of fullerene molecules caused by donor-acceptor complexes C60-NMP formation. Based on small-angle neutron scattering, mass spectrometry and spectrophotometry data was shown that restructuring of fullerene clusters as a result of C60?NMP system dilution is occurred via cleavage of fullerene monomers.
