A. Ferri et al., NEXAFS spectroscopy investigation on the electronic structure of newly synthesized Pt(II)/Zn-porphyrinato assemblies, SURF INT AN, 30(1), 2000, pp. 407-409
Spectroscopic investigations on the electronic structure of thin films of v
arious Zn-porphyrinato/Pt assemblies, consisting of a Zn-porphyrinato (ZnPf
) macrocycle inserted between bis(phosphine)platinum(II) centres, were carr
ied out by means of synchrotron radiation-induced near-edge x-ray absorptio
n fine structure (NEXAFS) spectroscopy at the third-generation storage ring
ELETTRA and at SuperACO, The spectra of the monomeric ZnPf and of the porp
hyrin-free base were also investigated for comparison. Modifications occur
mainly at the N K-edge, when Zn metallation is carried out, arising from ni
trogen deprotonation, and significant changes are also observed upon linkag
e between subunits, Copyright (C) 2000 John Wiley & Sons, Ltd.
