Abstract

The characterization of iodine counterions in doped fluorogallium(III) porphyrins is reported and the synthesis of a 129I 2 doped complex is described. The presence of I 3 − and I 5 − anions was enhanced on the basis of Raman spectroscopy data. The analysis of 129I Mössbauer spectra allowed determination of the presence of I − and the relative amounts of I −, I 3 −, I 5 − species. Additional results obtained by ESR spectroscopy showed the localization of the positive charge on the porphyrin π-ring system. Furthermore, the X-ray diffraction measurements enhanced two different lattices corresponding to the porphyrin and iodine chains respectively.
