Summary: This study presents a novel metal/anion-coordination co-driven strategy for the synthesis of nanoscale supramolecular metallocycles with unique topology and desired chirality. The enantiomeric Janus-type metallocyclic strips are formed through the synergistic coordination of sulfate anions and Co-II ions to a bifunctional chiral ligand. The chirality is derived from two types of helical chiralities, namely triply twisted Mo''bius ring and circular helicate, which represent a new phenomenon in metal-organic complex systems.

Summary: A stable mixed-valent uranium-based metal-organic framework with a unique three-dimensional structure was successfully synthesized, serving as a dual-responsive fluorescence temperature sensor. The fluorescence enhancement at low temperature (77 K) is significantly higher than at room temperature due to the decrease of nonradiative decay, which presents potential applications in the understanding and utilization of actinides in this oxidation state.

Summary: This study demonstrates the preparation of main-chain organometallic polymers using Janus NHC linkers and polynuclear cluster nodes for the first time. The crosslinked framework Co4S4-MCOP undergoes reversible electron transfer in the solid state and discrete molecular cluster species can be excised from the framework through digestion in solutions of excess monocarbene. Additionally, a synthetic route to monodisperse framework particles is shown via coordination modulation.

Summary: This study describes the synthesis and structures of nitrile complexes of V (N[(t) Bu] Ar) (3), 2 (Ar = 3,5-Me2C6H3). The thermochemical and kinetic data for their formation were determined using various techniques. The extent of back-bonding from metal to coordinated nitrile reveals a different role of electron donation compared to the related complex Mo (N[(t) Bu] Ar) (3), 1. Kinetic studies show similar rate constants for nitrile binding to 2, but the activation parameters depend on the nature of R in RCN. Density functional theory (DFT) calculations support the formation of a π-stacking interaction between a pendant arene of the metal anilide and the arene substituent on the incoming nitrile in favorable cases.

Summary: This paper presents the synthesis, characterization, and biological properties studies of a series of 5 coordination compounds based on binuclear core [Mo(V)2O2S2]2+ with thiosemicarbazones ligands bearing different substituents. The structures of the complexes in solution are determined using MALDI-TOF mass spectrometry and NMR spectroscopy, and compared to single-crystal X-Ray diffraction data. The antifungal and antioxidative activities are explored and the coordination compounds show higher potential compared to the uncoordinated ligands. DFT calculation provides support to the solution studies and explains the antioxidative properties of these systems by determining the most stable isomers and HUMO and LUMO levels.

Summary: By employing a multi-functional self-stabilization modification strategy involving trace Mg bulk doping, surface gradient Ti doping, and BaTiO3 dot coating, the challenges faced by LiCoO2 in terms of limited cycling stability at high voltage have been effectively addressed. Ti surface gradient doping strengthens the particle structure rigidity and mitigates irreversible oxygen redox at high voltage, leading to improved cyclic performance of LiCoO2 under 4.6 V high-voltage.

Summary: A Janus separator composed of functional layers on anode/cathode sides is designed to simultaneously solve the issues of Zn dendrite growth, polyiodide shuttle effect, and sluggish I-2 redox kinetics in Zn-I-2 batteries. The cathode layer with Fe nanoparticles-decorated single-wall carbon nanotubes effectively anchors polyiodide and catalyzes the redox kinetics, while the anode layer with cation exchange resin repels detrimental ions and improves the stability of cathode/anode interfaces. The Janus separator enables outstanding cycling stability and high-areal-capacity of Zn-I-2 batteries.

Summary: This study evaluates the migration and removal of redox sensitive elements (RSEs) at the sediment-water interface (SWI) off the Changjiang Estuary by examining the porewater and solid RSEs. The concentrations of porewater and solid RSEs decrease with depth, and the removal of Mo is mediated by Fe-S phase while the removal of U is microbial-mediated reduction. The peaks of dissolved nitrate, Fe2+ and acid volatile sulfur (AVS) correspond to the downward removal of V, U and Mo, and the upward shift of RSE peaks in porewater reflects the occurrence of hypoxia in summer.

Summary: The reactions of a calcium acenaphthene-1,2-diimine complex with phenazine and 4,4'-bipyridine result in electron transfer and the formation of dimer and coordination polymer, respectively. However, the reaction with 1,3-bis(4-pyridyl)propane leads to the formation of another coordination polymer without electron transfer. The compounds are characterized by various analytical techniques, and the presence of ligand-localized unpaired electrons is confirmed.

Summary: The hydrogen evolution activity of PS-double-layered photocatalysts was studied in the presence of redox-reversible electron donors. The polyoxometalates acted as effective electron donors and the photocatalyst showed an apparent quantum yield of 0.39% in the initial hour. Energy transfer deactivation from photoexcited PS* to surface-immobilized polyoxometalates was identified as the reason for lower quantum yield.

Summary: One-directional electron transport is crucial for efficient Z-scheme water-splitting photocatalysis. A photoredox cascade catalyst was synthesized to mimic natural photosynthesis's electron transport chain, using Pt-TiO2 nanoparticle catalyst, two photosensitizers (RuCP6 and RuP6), and a visible-light-transparent electron mediator (HCRu). The catalyst, named PRCC-1, exhibited the highest initial apparent quantum yield (iAQY = 2.23%) among dye-sensitized TiO2 photocatalysts, and successfully produced hydrogen using hydroquinone monosulfonate as the hydrogen source.

Summary: We propose a partially-oxidised bimetallic Mo-Pt subnanoparticle (Mo4Pt8Ox) that facilitates thermally-driven CO2 hydrogenation to CO at room temperature and atmospheric pressure. A mechanistic study elucidated the entire catalytic cycle of the reaction, from CO2 activation to catalyst reactivation. DFT calculations showed that alloying with Mo decreases the activation barrier by weakening CO adsorption, presenting a potential pathway for low-energy CO2 conversion.

Moreover, PRCC-1 successfully produced hydrogen using hydroquinone monosulfonate (H2QS-) as the hydrogen source.

Summary: Molecular crystals of Pt(ii) complexes with metallophilic interactions can exhibit bright assembly-induced luminescence with colour tunability. However, their brittleness hinders their application in flexible optical materials. In this study, the elastic deformation of crystals of polyhalogenated Pt(ii) complexes was achieved, resulting in bright luminescence. The crystal of [Pt(bpic)(dFppy)] showed ligand-centred emission, while the co-crystal of [Pt(bpic)(dFppy)] and [Pt(bpic)(ppy)] exhibited metal-metal-to-ligand charge transfer emission with a significantly higher emission quantum yield.

Summary: The acid-base properties of amphoteric crystalline YNbO4 are adjusted by impregnating phosphate groups, resulting in materials with increased activity and selectivity in glucose dehydration. The introduction of phosphate groups leads to the optimal catalyst, 5P-YNbO4, which exhibits 50% selectivity at 75% conversion. The catalyst can be deactivated due to carbon deposits, but its activity can be completely recovered through washing and calcination.

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.
