Summary: In this study, the catalytic properties of pincer platinum complexes in alkyne hydrosilylation were investigated under both photo and thermal conditions. The results showed that visible light-induced hydrosilylation was more efficient, requiring lower catalyst loadings and allowing room temperature reactions. The platinum complexes acted as both photosensitizers and catalysts, enabling bond breaking/forming transformations. The reaction selectivity differed under photochemical and thermal conditions, with the photoinduced process exhibiting enhanced regio- and stereoselectivity.

Summary: The properties and reactivity of metal complex photocatalysts for solar-to-fuel conversion can be controlled by the molecular design of their ligands. In this study, rhenium(I) tricarbonyl polypyridyl compounds with different N-heterocyclic ligands were investigated as photocatalysts for reducing CO2 to CO. These complexes showed exceptional photocatalytic performance, with significantly increased TONCO values compared to the unsubstituted parental complex. The presence of N-heterocyclic substituents enhanced the visible-light absorption properties, favored the kinetics and thermodynamics of the photocatalysis, inhibited deactivation of the photocatalysts, and unlocked an alternative CO2 photoreduction pathway.

Summary: This study presents a redox-neutral intramolecular dearomative spirocyclization induced by visible light, catalyzed by a phenolate anion-derived photocatalyst to deliver spirocyclohexadienone. Mechanistic experiments show that aryl halide is reduced to an aryl radical via single-electron transfer (SET) process under visible light irradiation. The electrophilic addition of an aryl radical with the phenolate anion moiety gives a radical anion intermediate, which recycles the photocatalyst by a second SET process.

Summary: Light-assisted antibacterial therapy, especially using visible light, has shown great potential as an alternative to antibiotic therapy. Recent research has focused on using near-infrared light irradiation to kill bacteria through hyperthermia and radical oxygen species. However, this study presents a visible light responsive organic-inorganic hybrid material for efficient treatment of bacterial infection. By capturing bacteria electrostatically and utilizing visible light through a Schottky junction, the material exhibits excellent antibacterial properties both in vitro and in vivo. This research highlights the potential of organic-inorganic materials in bio-photocatalysis and antibiotics-free treatment of wounds.

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.
