Summary: The lysozyme binding affinity and electronic properties of [ReX (CO)(3)(terpy-κN-2(1),N-2)] (X = Br− and triazolate(COOCH2CH3,CF3)) were reported, with the triazolate compound showing a red shift of the MLCT band in less polar solvents possibly due to negative solvatochromism. The triazolate complex was prepared through a [3 + 2] cyclo-addition click reaction, while the bromo compound reacted with lysozyme forming adducts with Re(CO)(3)(+) fragments.

Summary: Combining molecular metal complexes with coordination polymers offers an effective strategy for developing efficient noble metal-free CO2 photocatalysts. In this study, two novel Zr-containing bimetallic coordination polymers were successfully synthesized and applied for CO2 photoreduction to selectively produce CO. The catalytic performance of Co-Zr was found to be better than that of Ni-Zr, and the difference between these two catalysts was analyzed in terms of band structure and charge migration ability.

Summary: In this study, a decametric metal-organic cage, pentagonal prism Mn20LC10, was developed based on Tpy-Mn(II)-Tpy connectivity, with Mn(II) serving as a linker to provide good photosensitivity. This metal-organic cage exhibited enhanced 1O2 production, fast conversion time, recyclability, and substrate versatility in the photooxidation of benzaldehyde due to improved intersystem crossing ability. Remarkably, the abundant active sites of Mn20LC10 enabled its photooxidation under solvent-free and daylight conditions. This work offers potential approaches for the development of inexpensive, green, and low-cost photosensitizer systems.

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: Na-ion batteries (NIBs) have attracted great interest as a potential technology for grid-scale energy storage due to the wide distribution, low cost, and environmental friendliness of sodium resources. However, their implementation is hindered by low rate capability and cycling stability caused by the large ionic size of Na+. In this study, a three-dimensional nanoarchitectured coral-like CoSe2@N-doped carbon (CL-CoSe2@NC) was synthesized, and it exhibited improved sodium storage properties with better electrode kinetics and a stable SEI film.
