Valence zone electronic structure of phthalide-based polymers

Abstract X-ray photoelectron spectra of phthalide-based polymers and ultraviolet photoelectron spectra of monomers have been recorded. Interpretation of the first bands of polymers has been carried out on a basis of comparison with ultraviolet photoelectron spectra of monomers. X-ray photoelectron spectroscopy has been used observe changes in the ionization energy of the π-band in polypthalide induced by doping using I.
