Intense satellites in the N 1s x-ray photoelectron spectra of certain metalloporphyrins

Electroactive polymeric material with condensed structure on the basis of magnesium(II) polyporphine

“…for the monomer (curve 1) and film type I (curve 2), this ratio changes to about 65% : 35% for film of type II (curve 3), without peaks for oxygen-containing bonds. This structure for the former systems corresponds perfectly to literature data for pure Mg(II) porphyrin, MgTPP [25]. The spectrum for type II is intermediate between those for pure Mg(II) porphine/porphyrin and for metal-free porphine/porphyrin, in which both components in the N 1s spectrum should roughly be of equal intensities, i.e.…”

Magnesium(II) polyporphine: The first electron-conducting polymer with directly linked unsubstituted porphyrin units obtained by electrooxidation at a very low potential

“…The shapes of all elements correspond well to literature XPS data for porphyrins, in particular the above shape of the N 1s spectrum (including the position and the relative intensity of the shoulder) reproduces nicely those that for monomeric MgTPP [37]. The conclusion on the porphine ring conservation is also in conformity with the absence of carbon-oxygen (286-289 eV [38][39][40]) or nitrogen-oxygen (403-407 eV [41]) bonds in C and N spectra for these films.…”
