Corroles are tetrapyrrole macrocycles with promising applications in various fields of science. Here, we present a multi-technique strategy based on density functional theory (DFT) calculations, element-specific X-ray spectroscopy techniques and in situ atomic force microscopy (AFM) to unravel the electronic ground structures and the oxidation states of the prototypical Mn-5,10,15-tris(pentafluorophenyl)corrole complexes as well as of their thermally induced derivatives adsorbed on Ag(111).
Our results, in particular the theory-assisted interpretation of Mn photoemission and absorption fine structure spectra, enable a comprehensive understanding and a deep insight into the on-surface chemistry of such complex molecular systems on the atomic-scale level.
