Evidence of Protonated and Deprotonated Forms of Symmetrical and Asymmetrical Lutetium(III) Porphyrin Double-Deckers by H-1-NMR Spectroscopy
Protonated and deprotonated formulas for the symmetrical and asymmetrical Lu(III) porphyrin double-deckers have been investigated by H-1-NMR spectroscopy. Experiments in CDCl3 and DMF-d(7) by various techniques show and confirm unambiguously the solvent-dependent character of the proton present on the title complexes.
