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: This article provides an overview of the application of diruthenium(ii,iii) paddlewheel complexes for anticancer purposes. The use of this coordinative construct allows for combining the pharmacological properties of the dimetallic ruthenium center with specific carboxylate ligands to produce new entities with improved biological profiles. These systems also enable multiple drug deliveries to the target site, but chemico-physical aspects need to be considered for effective complex design.

Summary: Careful optimization of reaction conditions allowed access to the particularly small tetraruthenium macrocycle (Ru2Ph)-Ru-2-Croc, enabling various oxidized forms to be electrochemically characterized and scrutinized by spectroscopy. The study revealed that the mixed-valent species within the macrocycle are strictly charge-localized on the metal-organic Ru2Ph entities, with minimal involvement of the croconate ligands. The observed redox differences were attributed to electrostatic and inductive effects rather than electronic coupling, making (Ru2Ph)-Ru-2-Croc a true pretender in terms of redox behavior.

Summary: The synthesis of a series of trans-heteroleptic paddlewheel diruthenium(II, II) complexes with various hydroxy-substituted benzoate ligands is reported. The redox properties are linearly dependent on the acidity of the OH-substituted benzoic acids, but do not depend on the number of ortho-substituted hydroxy groups. The unexpected electron-withdrawing character of the o-OH groups could be attributed to the direct effect of intramolecular hydrogen bonding on the charge density on the carboxylate oxygen.

Summary: Paddlewheel-type dirhodium (Rh2) complexes with N,N'-bridging ligands exhibit redox activity and can adopt four oxidation states (Rh23+, Rh24+, Rh25+, and Rh26+) based on the coordination ligands at the equatorial and axial positions. N,N'-bridging ligands possess strong r-donating ability, resulting in destabilization of p*(Rh2) and d*(Rh2) orbitals while strongly coordinating to the metal center. This leads to unique near-infrared absorption and electrochemical properties in Rh2 complexes with N,N'-bridging ligands. This review summarizes the synthesis, crystal structures, electrochemical behaviors, absorption features, and magnetic properties of paddlewheel-type Rh2 complexes with N,N'-bridging ligands.

Summary: This study examines the molecular structure, electrochemistry, spectroelectrochemistry, and electrocatalytic oxygen reduction reaction (ORR) features of two Co-II porphyrin (2.1.2.1) complexes with Ph or F5Ph groups at the two meso-positions of the macrocycle. Single crystal X-ray analysis reveals a highly bent, nonplanar macrocyclic conformation of the complex resulting in clamp-shaped molecular structures. Cyclic voltammetry and UV/Vis spectroelectrochemistry experiments suggest that the first electron addition corresponds to a macrocyclic-centered reduction and the first oxidation process involves a metal-centered Co-II/Co-III process. The clamp-shaped complexes exhibit selectivity towards the 4e(-) ORR pathway, producing H2O, during heterogeneous ORR in 0.1 M KOH.

Summary: A mono-DMSO cobalt meso-CF3 corrole was synthesized and characterized, and its spectral and electrochemical properties in nonaqueous media were investigated. The results indicated that the presence of electron-withdrawing trifluoromethyl substituents at the meso-carbon atoms of the macrocycle enhanced the ease of reduction and hindered oxidation. The effects of DMSO, pyridine, and cyanide anions on the compound's electrochemistry and spectral properties were examined, showing the formation of a bis-CN adduct with only two molar equivalents.

Summary: A new family of fi-dicyanovinyl (DCV)-appended corroles, MTPC(MN), were synthesized and their spectroscopic and electrochemical properties were investigated. The results showed that the fi-DCV group had a pronounced substituent effect on the physicochemical properties, making the MTPC(MN) derivatives easier to reduce and more difficult to oxidize. The DCV metallocorroles CuTPC(MN) and AgTPC(MN) acted as chemodosimeters for selective cyanide ion detection, while (PPh3)CoTPC(MN) acted as a chemosensor for cyanide ion sensing.

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.
