Summary: A series of asymmetrical terpyridine ruthenium-TAA complexes were prepared and characterized, and their bonding and electronic properties were studied by spectro-electrochemistry and theoretical calculations. The electrochemical results showed two successive single-electron redox processes, and the near-infrared spectroscopy revealed multiple absorption characteristics of the complexes. The electron coupling parameters obtained from the analysis of mixed-valence states decreased with bridge conjugate extension, consistent with the DFT calculation results.

Summary: Electrochemistry has promising potential in studying interfacial electron transfers and redox reactions, but the lack of molecular structural information hinders understanding of complex systems. Complementary optical and spectroscopic techniques that provide electronic and structural identification of reactants and products are necessary for visualizing the electrochemical processes. Recent advancements in instrumentation and nanostructures allow for spatiotemporal resolution of molecules during complex reactions, enabling the optical revelation of intermediates, mechanisms, and rates, which are essential for fundamental and theoretical electrochemistry. This short review introduces the latest feasible optical and spectroscopic techniques, including dark-field, Raman, infrared, and ultraviolet-visible-near-infrared opto-and spectro-electrochemistry, for electrochemists to begin with.

Summary: This study describes the amoebicidal activity of five 2-(Z-2,3-diferrocenylvinyl)-4X-4,5-dihydrooxazole derivatives on Entamoeba histolytica trophozoites, as well as the physicochemical, experimental, and theoretical properties that can be used to describe the antiproliferative activity. The growth inhibition capacity of these organometallic compounds is strongly related to a fine balance between the compounds' redox potential and hydrophilic character. Compound 3d presents the highest antiproliferative activity of the series with an IC50 of 23 μM. However, the results of this work provide a pipeline to improve the amoebicidal activity of these compounds through the directed modification of their electronic environment.

Summary: In this study, the photophysical properties of transition metal complexes were fine-tuned by targeted design of a N<^>C-C<^>N type ligand. The mononuclear complex Pt-1 exhibited red phosphorescence, while the dinuclear complex Pt-2 showed near infrared phosphorescence. The phosphorescence of the complexes was quenched in the presence of molecular oxygen, generating singlet oxygen molecules. Pt-1 had a unique dual emission ability, which was beneficial for cellular imaging.

Summary: We investigated the photo-physical properties of three mononuclear Ir(III) complexes fac-Ir(dppm)3, Ir(dppm)2(acac), and Ir(ppy)2(acac). Among them, Ir(dppm)2(acac) showed high emission efficiency and a remarkably short radiative decay time. Our analysis of the electronic structure revealed that the high phosphorescence rate of Ir(dppm)2(acac) is attributed to the alignment of the dppm ligands and the large chromophore formed by the (het)aryl rings. These findings provide molecular design principles for developing phosphors with enhanced emission rates.

Summary: Using femto-second time-resolved spectroscopy, we investigated the intersystem crossing times (ISC) of two Cu(I) dimers, Cu2Cl2(dppb)(2) 1 and Cu2Cl2((NP)-P-bool AND)(2) 2. The ISC times ranged from 39 ps (1) to 3.7 ps (2). The radiative phosphorescence decay time (iota(r)(T1)) and zero-field splitting (ZFS) showed a similar trend, with values of 4.2 ms and ZFS < 1 cm(-1) for 1, and 45 µs and 15 cm(-1) for 2, respectively. Quantum mechanical considerations and TD-DFT calculations allowed us to establish a correlation between these photophysical properties and spin-orbit coupling (SOC), particularly in the triplet state T-1.

Summary: Cancer is a leading cause of death worldwide. This review emphasizes the significance of metal-catalyzed azide-alkyne cycloaddition reactions in synthesizing ferrocenyl-x-1,2,3-triazolyl-R compounds with anticancer activity. The review discusses over 160 ferrocenyl-triazoles and their classification into four categories based on their chemical properties. The study demonstrates that copper-catalyzed azide-alkyne cycloaddition reactions are particularly important in yielding the highest number of ferrocenyl-x-1,2,3-triazolyl compounds with anticancer activity. Oxidative stress and reactive oxygen species generation are identified as common mechanisms through which the ferrocenyl moiety contributes to the anticancer activity of 1,2,3-triazolyl derivatives. The review contains 23 figures, 24 schemes, and 208 references.(c) 2022 Elsevier B.V. All rights reserved.

Summary: Prostate cancer is a major health issue and the second most common cancer in men. Photodynamic therapy (PDT) is a non-invasive method that uses photosensitizers and light to induce cell death with minimal side effects. However, some photosensitizers used in PDT have low solubility in biological media, requiring functionalization or vectorization for effective internalization. This study used arene-ruthenium cages to deliver photosensitizers to prostate cancer cells. The results showed that most of the compounds induced cytotoxic effects on prostate cancer cells, with confirmed internalization in the cytoplasm. The presence of metals in the photosensitizers decreased the effectiveness of PDT, and in some cases, completely eliminated its effect.

Summary: Gold(II) complexes have been less utilized in catalysis compared to their gold(I) and gold(III) counterparts. However, gold(II) complexes offer potential in homo-coupling and cross-coupling reactions, as they are more easily accessible through simplified oxidation and reduction processes. Gold(II) exhibits characteristics of both soft acid gold(I) and hard acid gold(III). This review explores the unique reactivity and potential applications of gold(II) species, highlighting their significance in catalytic transformations.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.
