Summary: Using a chelating C,C'-bis(silylenyl)-ortho-dicarborane ligand, a monoatomic zero-valent Ge complex was synthesized, showing different reactivities towards reductants and oxidants due to the redox non-innocent nature of the carborane scaffold. The reduction and oxidation of the Ge complex resulted in the formation of dianionic or dicationic bis(silylene)-supported Ge complexes with distinct properties.

Summary: Photoredox catalysts (PCs) have advanced organic chemistry by utilizing reactive electrons in excited states, with chemists seeking new promising PCs. Quantum chemical simulations offer efficient exploration of chemical space. A theoretical protocol was designed to predict excited-state redox properties with high accuracy, focusing on three critical factors: solvent effects on geometries, Hartree-Fock exchange, and double-excitation character.

Summary: Four new structurally similar dinuclear oxorhenium(V) complexes have been synthesized and characterized, showing little variation in spectroscopic features. All complexes exhibit a bent Re-O-Re core and distorted octahedral coordination geometry. A reversible one-electron electrochemical process is observed at approximately 0.84 V vs. Fc(+)/Fc in all four complexes, with a slight destabilization of the oxidized Re(VI) center when changing the terminal halide from chloride to bromide.

Summary: The reaction between TaMe3Cl2 and the rigid acridane-derived trisamine H3NNN produces the tantalum(V) complex [TaCl2(NNNcat)]. Subsequent reaction with dioxygen results in the formation of the oxido-bridged bimetallic complex [{TaCl2(NNNsq)}(2)O] through a four-electron reduction of O-2. The mechanism of O-2 activation was investigated using DFT calculations, revealing the binding of O-2 to the tantalum(V) center and subsequent scission to produce a terminal oxido-complex.

Summary: In this study, diruthenium-based cyanido-bridged asymmetrical compounds were used to investigate the electron transfer process. A series of new trinuclear complexes were synthesized and characterized, and their electron transfer properties were analyzed through UV-vis-NIR spectroscopy. The results show that increasing the electron-accepting capability of the electron acceptor is more effective in decreasing the electron transfer energy.

Summary: The study investigates the relationship between the structure and electronic properties of conjugated polymers through quantum mechanical calculations, providing a connection between the calculated electronic properties of monomers and the observed optical and electrical properties of their conjugated polymers. By synthesizing compounds with varying numbers of electroactive groups and optimizing their molecular structures using Density Functional Theory, the electronic properties of the monomeric structures and reactive regions on the molecule surfaces have been determined. Analysis of Total Density of State, Partial Density of State, and Mulliken charge has been performed to compare the ab-initio calculations of monomers with the optical and electrical properties of their conductive polymers.

Summary: Transition metal complexes are potential redox mediators for redox flow batteries due to their adjustable electrochemical potentials. However, there is a need for reliable and efficient tools to predict their reduction potentials. This study establishes a suitable density functional theory protocol for prediction by using experimental data of aqueous iron complexes with bidentate ligands, and cross-validates it with different complexes in the redox-flow literature. The accuracy of prediction is found to be more influenced by the solvation model than the functional or basis set. The smallest errors are obtained using the COSMO-RS solvation model (mean average error (MAE)=0.24 V), while a general deviation from experimental results is observed with implicit solvation models. For a set of similar ligands, linear regression can be used for correction (MAE=0.051 V for the initial set of iron complexes).

Summary: The study designed three tetraterpyridine ligands with variations in their core architecture to create spray-coated electrochromic assemblies of iron(II)-based metallosupramolecular polymer network films. These assemblies exhibited high coloration efficiencies and optical contrast, suitable for electrochromic devices. The ligand-structure induced differential metal coordination led to porosity and spectroelectrochemical diversification, enabling the creation of electrochromic patterns and images through a simple spray-coating technique.

Summary: Analyzing the atomic nature of reactive sites and trap states is crucial for adjusting catalysis and reducing surface voltage losses. Combining spectroelectrochemical and computational methods, the study investigated a model photocathode from the chalcopyrite family, revealing that voltage losses are related to traps induced by surface Ga and In vacancies, and catalysis occurs at specific sites. Avoiding the formation of Ga and In vacancies is essential for achieving high activity.

Summary: We studied the excited-state relaxation of the complex ReCl(CO)(3)(bpy) in acetonitrile and dimethylsulfoxide solutions using nonadiabatic TD-DFT dynamics. By simulating the time-dependent populations of spin-mixed states, we monitored the temporal evolution of singlet and triplet states, fitted the bi-exponential decay kinetics, and simulated the time-resolved fluorescence spectra. Analysis of structural relaxation and solvent reorganization helped identify the factors influencing the fluorescence decay time constants.

Summary: Doped carbon materials, especially F-doped carbon catalysts, have gained significant attention as metal-free catalysts for oxygen reduction reactions and as corrosion-resistant supports for Pt and non-Pt nanoparticles. F-doped carbon materials possess unique properties and greatly improve the activity and durability of the ORR compared to N-doped carbon materials. The high electronegativity of F-doping can efficiently modify the electronic band structure of carbon materials, favoring the ORR. This review systematically discusses the effect of F-doping/F co-doping on the electrocatalytic reduction of O2 in acidic and alkaline conditions, the stability and durability of fuel cell catalysts, and provides guidelines for working with F-doped carbons. Future research directions on F-doped carbons are also proposed to bridge the gap between laboratory-scale assessments and commercial applications.
