 (a) Schematic of the liquid cell for XAS analysis of metal porphyrin complexes in aqueous solutions. XAS spectra of the central metals were obtained at the Fe or Co L2,3-edge and those of ligands were obtained at the N K-edge. The hydration of the metal porphyrin complex was also investigated using N K-edge XAS. (b) N K-edge XAS spectra of FePPIX, CoPPIX, and PPIX in aqueous solutions. The C=N π* peaks of the ligands reflect metal‒ligand delocalization of the metal porphyrin complexes.
