The electronic and local atomic structure of lutetium metalloporphyrins Lu(acac)TPP and precursor tetraphenylporphyrin (TPP) have been studied by X-ray photoelectron spectroscopy (XPS) and absorption spectroscopy (XAFS). The XPS spectroscopy data show changes in the electronic structure of tetraphenylporphyrins under incorporation of the lutetium atom: a redistribution of the electron density between the nitrogen atoms of the pyrrole- and aza- group and appearance of one broadened peak of the N1s state. The integer trivalent state of the rare-earth metal (Lu 3+ ) in metalloporphyrins has been confirmed by both XPS and XAFS methods.
