Effect of a single methyl substituent on the electronic structure of cobaltocene studied by computationally assisted MATI spectroscopy

“…Since discovery of the intriguing sandwich structure of (Cp) 2 Fe seven decades ago 1,2 metallocenes have become one of the most prominent classes of organometallics. During last years, cobaltocene and its substituted derivatives have been attracting special interest due to their relevance to modern catalytic systems, [3][4][5] sensors, [6][7][8] metallopolymers, [9][10][11][12] and molecular magnets, 13 as well as to the materials for hydrogen evolution, [14][15][16] batteries, [17][18][19][20][21][22] solar cells [23][24][25] and spintronics. 13,26,27 The adiabatic ionization energy I ad.…”

Probing the Electronic Structure of Prussian Blue and Analog Films by Photoemission and Electron Energy Loss Spectroscopies

“…In an innovative preparation route, HCMs and CNTs were combined as thin film composites resulting in outstanding electrochemical stability [33] . Briefly, inorganic salts of [M′(CN) 6 ] coordination complexes react with metal species from CNT cavities in an aqueous solution, and previous investigation indicates that CNTs act as a p‐dopant, improving the interaction with HCMs [10,33–38] . Although HCM/CNT thin film composite materials were examined extensively, variations in their performance depending on chemical treatments must be better understood.…”

To this aim, the characterization of HCM/CNT materials using electron spectroscopic techniques could further elucidate how the electronic structure and chemical composition are affected by different chemical environments.…”

Controlled Crystallization of Carbon-blended Prussian Blue Analogs for Advanced Sodium-Ion Batteries

“…Numerous studies of notable value have been undertaken to investigate the potential of PBA electrodes for employment in SIBs. Specifically, PBAs based on Mn/Ni/Co/Cu have been extensively explored, as documented in a plethora of literature sources. − In contrast, low-priced and abundant Fe-based PBAs-A x M­[Fe­(CN) 6 ] y (A = Li, Na, K, etc., M = Fe, Co, Ni, etc., 0 < x < 2, 0 < y < 1) still occupy an important position, relying on the electrochemically active redox sites of Fe, which can contribute high energy density. In the three-dimensional open framework structure, Fe and M atoms are situated on corner-sharing octahedra that are interconnected by linear anionic cyanide ligands placed on alternating corners of the cubes .…”
