Summary: This study reports the self-assembly of a donor-acceptor system into nanoscopic structures and the photo processes occurring within these structures. The efficient photoinduced electron transfer within the assembled system leads to the formation of stable radical ions. The stability of the radical ions is attributed to the fast reaction process that slows down the back electron transfer.

Summary: High-entropy metal disulfide (HES2) colloid clusters were synthesized and used as anode materials for potassium-ion storage devices. The large configuration entropy stabilizes HES2's crystal structure, reduces the shuttle effect, and extends cycling life up to 1800 cycles. HES2's structure enhances electrochemical reactions and allows for better anchoring of potassium polysulfide, leading to excellent performance in potassium-ion full battery and hybrid capacitor applications.

Summary: With the use of anion template-driven self-assembly, we have achieved precise control over the shape and size of silver nanoclusters, reporting the atomically precise structures of Ag37 and Ag46. The results reveal that Cl- ions serve as both local and global templates in Ag37, while CrO42- ions function as local templates with Cl- ions as global templates in Ag46. By utilizing the deep cavity of thiacalix[4]arene with an extended phenyl group, Ag46 has been successfully used as a host material for dye adsorption depending on the charge and size of organic dyes. The study fills the knowledge gap in understanding the directing role of heteroanions in dictating the shape and size of nanoclusters at the atomic level.

Summary: By fusing two Co6Se8(PEt3)(5) superatoms into [Co6Se8(PEt3)(5)](2) dimer, a magnetic unit with a spin moment of 2 mu(B) is formed. The dimer has a low ionization energy, allowing it to donate charge during the formation of cluster assembled materials. Adding electrons to the dimer may enhance the magnetic moment by neutralizing the charged cluster, revealing a strategy for stabilizing magnetic moments in ligated cluster assemblies.

Summary: Photocatalytic reduction technique is a promising method for treating Cr(VI)-containing wastewater, but finding efficient photocatalysts for practical applications is a challenge. Inorganic-organic hybrid metal chalcogenides, such as the synthesized BITS, show great potential as photocatalysts for Cr(VI) reduction due to their unique layered structure. BITS exhibited outstanding photocatalytic performance for reducing Cr(VI) under visible light irradiation, surpassing other materials like P25, In2Se3 nanoparticles, and SnSe2 nanosheets. It also demonstrated strong resistance to interference from different ions and maintained its excellent performance in various water bodies. Additionally, BITS showed high efficiency for Cr(VI) reduction under sunlight irradiation. Research results highlight the potential of inorganic-organic hybrid metal chalcogenides as photocatalysts for treating Cr(VI) in wastewater.
