Summary: A new Ru polypyridyl complex with an N-heterocyclic carbene ligand was synthesized and characterized in this study. The complex exhibited strong absorption in the visible-light region due to the electron-donating nature of the carbene ligand, and showed efficient catalytic activity for visible light-driven CO2 reduction, with a reaction rate of 36.7 h(-1).

Summary: A new ruthenium polypyridyl complex was synthesized and characterized, showing instability and oxidation under aerobic conditions. The reaction provides insights into C-H activation with important implications for catalysis. Theoretical and experimental investigations suggest a two-step aerobic oxidative transformation with the formation of a diruthenium mu-peroxo intermediate as an alternative pathway for C-H activation.

Summary: QAP-C8, a pure organic dye based on QA with octyl side chains as the donor and PDA as the acceptor, was successfully used in both the photoanode and photocathode of photoelectrochemical cells. A tandem device with QAP-C8 as the photosensitizer achieved overall water splitting without an external bias under neutral pH conditions, showing a STH of 0.11%.

Summary: This study reports a Ru(II) complex (Ru-PDC3) that combines the light switch capability of a Ru(II) dipyridylphenazine complex with the well-known G4-selective ligand Phen-DC3 into a single structure. The complex exhibits the expected light switch effect and strong affinity for G4 structures, while also possessing a powerful G4 disrupting capability. Additionally, the complex is fully water-soluble and readily permeable to live cells.

Summary: Two metal-free calix[4]arene dyes with pyridyl anchoring groups were synthesized and applied in dye-sensitized photoelectrochemical cells, showing superior durability and photoelectroconversion properties compared to a comparative single-chain dye. The introduction of alkalinous pyridyl anchoring groups improved adsorption firmness on TiO2. The study provides inspiration for developing efficient and durable organic photosensitizers in photocatalytic water-splitting devices.

Summary: This paper reports two new tris-heteroleptic Ru(II) complexes with triphenylphosphine coordination, which show suitable photochemical properties for photochemotherapeutic applications. The study reveals that under visible light irradiation, the complexes exhibit increased activity due to the photoinduced substitution reaction of PPh3 ligand in the excited state. These complexes represent a new design motif for the selective release of PPh3 and CH3CN for use in photochemotherapy.

Summary: In this study, we synthesized a series of Ru(ii) metallacycles with multimodal chemo-phototherapeutic properties, which showed higher anticancer activity and better cancer-cell selectivity compared to cisplatin. The antitumor mechanism was attributed to the activation of caspase 3/7 and subsequent apoptosis. These findings suggest new potential applications of Ru(ii) metallacycles in biomedicine.

Summary: In this study, CuS nanoparticles are deposited on ZnO nanotube arrays for solar-driven water splitting. The CuS NPs have excellent light harvesting capacity, expanding the light absorption range and substantially boosting light absorption. The CuS NPs coupled on ZnO NTAs establish a type-II band alignment, leading to a significantly enhanced water splitting performance under visible light illumination. The photocurrent density of the ZnO/CuS NTAs photoanode is increased by 9 times compared to that of the pure ZnO NTAs photoanode.

Summary: A series of novel ruthenium(II) and iridium(III) complexes with different ancillary ligands and a PARP-1-inhibitory chelating ligand were designed and synthesized. The complexes exhibited potent antiproliferative activity on cancer cell lines, with the ruthenium(II) complexes being more cytotoxic. The most active ruthenium complex induced apoptosis in cancer cells through multiple mechanisms.

Summary: Various hybrid systems of metal-complex photocatalysts and semiconductor materials have been developed for photocatalytic CO2 reduction using the Z-scheme mechanism. This study focused on the photocatalytic activity of RuRu/Al2O3 in CO2 reduction by varying the adsorption density of RuRu. Increasing the adsorption density of RuRu led to a decrease in the production of the main product, HCOOH, due to the formation of Ru polymers. The addition of mononuclear Ru(II)-complex photosensitizers improved the photocatalytic activity of RuRu by supplying electrons to suppress its decomposition.

Summary: Cancer cells rely on glycolysis for energy but recent studies have shown that their mitochondria still play an active role. The study synthesized and characterized ruthenium compounds with triarylphosphine-containing bipyridyl ligands which showed high depolarizing capabilities on mitochondrial membranes in cancer cells. These compounds have the potential for anticancer applications due to their potency against cancer cells and low toxicity in zebrafish embryos.

Summary: Efficient and solvent-free SnO2 quantum dots-decorated V2O5 nanobelt catalysts were synthesized for controlling environmental pollution via photoelectrochemical water splitting. The modification with SnO2 QDs significantly influenced the optical properties of the V2O5 nanobelts. Optimized SnO2 QDs-decorated V2O5 nanobelts showed the lowest charge transfer resistance and capacitive behavior in 0.1 M NaOH electrolyte.

Summary: This study systematically analyzed the electrochemical, spectrochemical, and photophysical properties of a series of ruthenium polypyridyl complexes. The results showed that modifying the ligands can shift the absorption and emission energies, and revealed the interplay between red-shifting MLCT absorptions and accessing the dissociative (3)dd* states. This work provides important insights for the future design of ligands and complexes for photochemotherapies.
