Summary: An axially coordinated oligomer of ferrocene-based Sn(IV) porphyrin with C-60 was synthesized and characterized, showing no electronic interaction in the ground state among the photoactive components. However, efficient photoinduced electron transfer occurred under specific conditions, resulting in the formation of a stable charge-separated state. In addition, a prompt and stable photocurrent was generated in photovoltaic devices under irradiation with monochromatic light.

Summary: The combination of cobalt porphyrin molecule with graphene oxide forms efficient electrocatalysts for CO2 reduction reaction. The Co(III)TPPCl/GO nanocomposites synthesized via a chemical method exhibit better catalytic ability for CO2RR than the physically mixed Co(II)TPP+GO and/or Co(III)TPPCl+GO nanocomposites. The strong interaction between CoTPP and GO plays a key role in electrocatalytic CO2RR.

Summary: Chiral monodentate biaryl phosphines (MOPs) have been extensively studied as chiral ligands. The authors demonstrate a diverse synthesis method for structurally diverse MOPs containing both phosphorus and axial chirality. They employ a distinct strategy for diversity-oriented synthesis, enabled by the enantioselective cleavage of C-P bond, to create chiral Pd-II intermediates that can be transformed into enantioenriched MOPs with high diastereo- and enantioselectivities. These chiral MOPs show excellent catalytic properties in the asymmetric [3 + 2] annulation reaction, leading to the formation of chiral functionalized bicyclic imide.

Summary: The study found that soil media characteristics can vary greatly between systems despite having the same engineering specifications. Porewater SRP does not evolve uniformly with depth, emphasizing the importance of overall system design including redox conditions, infiltration rate, and vertical layering of different materials. The retention-release processes of SRP often occur at shallow depth, and hydraulic conductivity plays a key role in influencing SRP retention-release.

Summary: To overcome the limitation of sunlight in artificial photosynthesis, researchers have been exploring the use of molecular catalysts for two-electron water oxidation, which forms H2O2 instead of the conventional four-electron oxidation that produces O2. Among these catalysts, tin(IV)-tetrapyridylporphyrin (SnTPyP) has shown promising performance. By studying the protolytic equilibria of different species of SnTPyP in both ground and excited states, researchers have identified the most favorable catalysts for visible light-induced two-electron water oxidation in the molecular catalyst sensitized system of artificial photosynthesis.

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.

Summary: In this work, two metal organic frameworks (MOFs) containing {Cu2I2} clusters, Eu-CuI-INA and Sr-K-CuI-INA, were synthesized and characterized. Both materials have a three-dimensional structure with {Cu2I2} clusters coordinated by INA(-) ligands and Eu3+ or Sr2+ ions. The Sr-K-CuI-INA material exhibited sensitive fluorescence sensing behaviors towards cysteine and nitro-bearing molecules, showing potential applications in bio and explosive molecule sensing.
