Atomic and Electronic Structure of Metal–Salen Complexes [M(Salen)], Their Polymers and Composites Based on Them with Carbon Nanostructures: Review of X-ray Spectroscopy Studies

“…Research in recent years has been characterized by individual attempts to use the XPS method to obtain information on the chemical state of functional atoms in monomers and their poly-[M(Salen)] polymers, as well as on the atomic structure of these polyatomic systems [26,39,[43][44][45][46][48][49][50][51][52]114]. It should be noted that all the cited measurements of XPS spectra are mainly of a test nature, and most of them were performed on laboratory installations using X-ray tubes as radiation sources with low energy resolution and insuffi- It is important to note that X-ray absorption (NEXAFS, EXAFS) spectra can be measured in various modes such as transmission and fluorescence as well as total electron and Auger electron yield modes.…”

“…Therefore, the X-ray absorption and photoelectron spectroscopy methods are among the most informative experimental techniques for studying the local atomic and electronic structures of various polyatomic systems: molecules, complexes, polymers, etc. However, recent studies are characterized by only separate attempts to use the methods of X-ray core-level photoelectron spectroscopy (XPS) [8,26,35,37,39,40,[42][43][44][45][46][47][48][49][50][51][52] and valence-band photoemission spectroscopy (VB PES) [45,46,53], as well as X-ray absorption spectroscopy (near-edge X-ray absorption fine structure, NEXAFS, and extended X-ray absorption fine structure, EXAFS) [27,29,30,40,45,46,[52][53][54][55][56] to obtain information about the features of the electronic structure of [M(Salen)] complexes, their polymers, and composites based on them, as well as about the atomic structure of these polyatomic systems.…”

Improving the Adhesion of Multi-Walled Carbon Nanotubes to Titanium by Irradiating the Interface with He+ Ions: Atomic Force Microscopy and X-ray Photoelectron Spectroscopy Study

“…The improvement is due to a combination of two factors. Firstly, there is the high specific surface area of MWCNTs, which increases the electrical double layer capacity, and secondly, a conductive polymer contributes to the capacity through redox reactions (pseudo-capacity) [ 3 , 4 ]. However, the practical application of such a material is significantly hampered by the poor adhesion of MWCNTs to the conductive substrate.…”

Assembly of [Ni(Schiff)] Films on an Inert Surface: A Multiscale Computational Study

“…The complexes of transition metals with SalEn-type Schiff bases (SalEn = N , N ′-bis­(salicylidene)­ethylenediamine), [Me­(Schiff)], are of considerable interest as precursors for the formation of polymeric complexes. As compared to other electroactive materials, these complexes possess a variety of advantages such as a high thermal stability, reversible electrooxidation within a wide range of potentials, and high electron conductivity resulting in a high charge transfer rate. − Due to the unique electrochemical properties and the ease of chemical structure modification, such compounds are a promising class of materials for producing supercapacitors, batteries, and electrochemical sensors, as well as for the modification of electrode surfaces. − Despite an intensive investigation of the properties of such materials, there is still no consensus about the mechanism of electropolymerization of [Me­(Schiff)] complexes. ,,− The structure of the adsorptive surface layer largely determines the mechanism of consequent polymerization and the properties of the polymer obtained thereby. − Therefore, a molecular-level insight into the mechanism of aggregation of the complexes [Me­(Schiff)] can significantly improve the understanding of the polymer film assembly and provide clues both for the targeted optimization of the molecular structure of the complexes and for the improvement of the polymerization procedure.…”
