Abstract

The ESR spectra of petroleum pitch labeled with the stable copper-porphyrin complex and changes in the spectra due to pyrolysis are analyzed. It is concluded that the functions of carriers and traps for unpaired electrons in mesophase pitch are performed by anisotropic associates or crystallites sized about 2.0 nm. The intermodular interactions between the parallel layers of anisotropic associates may be significant. They increase when the molecular associates pass to the paramagnetic state and determine the preferable packing of the paramagnetic crystallites one over another.
