Spectroscopic investigations on the electronic structure of thin films of various Zn-porphyrinato/Pt assemblies, consisting of a Zn-porphyrinato (ZnPf) macrocycle inserted between bis(phosphine)platinum(II) centres, were carried out by means of synchrotron radiation-induced near-edge x-ray absorption fine structure (NEXAFS) spectroscopy at the third-generation storage ring ELETTRA and at SuperACO, The spectra of the monomeric ZnPf and of the porphyrin-free base were also investigated for comparison. Modifications occur mainly at the N K-edge, when Zn metallation is carried out, arising from nitrogen deprotonation, and significant changes are also observed upon linkage between subunit.

Abstract

Spectroscopic investigations on the electronic structure of thin films of various Zn-porphyrinato/Pt assemblies, consisting of a Zn-porphyrinato (ZnPf) macrocycle inserted between bis(phosphine)platinum(II) centres, were carried out by means of synchrotron radiation-induced near-edge x-ray absorption fine structure (NEXAFS) spectroscopy at the third-generation storage ring ELETTRA and at SuperACO, The spectra of the monomeric ZnPf and of the porphyrin-free base were also investigated for comparison. Modifications occur mainly at the N K-edge, when Zn metallation is carried out, arising from nitrogen deprotonation, and significant changes are also observed upon linkage between subunit.
