In Angew. Chem., Int. Ed. 42 (2024) e202403495, the question that I answered was whether depositing a radical monolayer can influence the magnetic properties of a "classical" ferromagnetic material such as cobalt. It was the first time that this aspect was explored. This was done by proposing a different way to look at the organic/ferromagnetic interfaces. By combining soft X-ray techniques such as XPS and NEXAFS and analyzing all details of the electronic structure of the interface, it is possible to predict its magnetic properties. In this case, the Blatter-pyr derivative, used for this investigation, is strongly hybridized with the surface. Changes in the core level spectra reflect the modification of the molecule and the cobalt electronic structures inducing a decrease in the magnetic moment of the cobalt atoms bond- ed to the molecules which, in turn, lose their radical character. Taking inspiration from the data analysis performed on electron energy loss spectroscopy (EELS), I have adapted it to the NEXAFS spectra to quantify the differences in the spectra before and after evaporation, calculating the I(L3)/I(L2) ratio. The I(L3)/I(L2) ratio is lower after the radical layer deposition, indicating lower d orbital occupancy. Considering methods previously used for EELS spectra; it is also possible to obtain a numerical estimate of the d orbital occupancy that confirms the chemisorption of the Blatter-pyr with charge transfer from the cobalt surface. After the publication of this paper, I was invited to write a "Feature article" to be published in Chemistry-A European Journal (in preparation) on this new development.
