Lead-free halide double perovskites with broadband self-trapped exciton emission have excellent properties such as good visibility, diverse colors, and simple designs, making them outstanding materials for anticounterfeiting and information encryption applications. In this study, we successfully synthesized lead-free halide double perovskites with dual emission centers by doping Sb3+ and Cr3+ into Cs2NaScCl6. The blue emission (445 nm) originates from the self-trapped exciton emission of the [SbCl6]3– octahedra, while the near-infrared emission (980 nm) comes from the luminescence of the Cr3+ ions. The near-infrared emission (980 nm) achieved a quantum efficiency of up to 71% through efficient energy transfer among multiple emission centers. Finally, various anticounterfeiting patterns were realized through screen printing samples. The research results provide inspiration for designing lead-free halide perovskites with efficient tunable luminescent properties.","PeriodicalId":40,"journal":{"name":"Inorganic Chemistry","volume":"4 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144130152","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Developing new methods for capturing and separating elemental bromine from brine or seawater is attractive and challenging. Here, we demonstrated that a highly stable Cd-MOF allows for reversible bromine uptake from either vapor or a brine phase at ambient temperature. Fast adsorption for a low concentration of Br2 indicated its potential application in bromine capture from seawater. Recycling experiments testified to the reusability of Cd-MOF as a bromine capture material. The adsorption mechanism was elucidated for the first time by single-crystal structural analysis. Three adsorption pathways, including physically adsorbed Br2, anion exchanged Br5– and chemically generated N–Br bonds, synergistically captured bromine into the framework. The strong Br···Br interactions between Br2 molecules and Br– anions and N–Br bonds play an important role in fixing three Br2 molecules in the framework. Bromination reactions for six aromatic substrates under ambient conditions were also carried out by this Br-loaded material, and the results showed a higher monobromination yield for methylphenols.","PeriodicalId":40,"journal":{"name":"Inorganic Chemistry","volume":"79 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144133577","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

NaVO demonstrates the feature of a single-ion conductor, exhibiting a sodium ion transference number of 0.88, which can provide selective passage for Na+ migration with the anionic V-O-V layer unmoved. Impressively, the redox reactions and electron transfer between I- and V5+/4+ (such as VV/IV2O5 + 2I- ↔ VIV/III2O5 + I2) are beneficial for Na+ (de)intercalation (from)into NaVO. Meanwhile, the inner wall of the layered NaVO is occupied by the preinserted Na+, which can retard the penetration of the large-sized iodide/polyiodides and impede them shuttling from the iodine-cathode chamber into the anode side. Moreover, the exposed (001) crystalline plane of NaVO enables the adsorption and stabilization of the I+ intermediate via charge transfer of I → O → V, which can facilitate multielectron conversion of 2I- → I2 → 2I+, resulting in an increased capacity. Therefore, a NaVO/poly(vinylidene fluoride) PVDF quasi-solid-state composite polymer electrolyte (CPE) is fabricated, which presents a high σ and large tNa+ with interfacial compatibility.

On the other hand, the ruthenium(III) complexes generally show low solubility and stability in an aqueous environment but exhibit some toxicity associated with unspecific delivery. For these reasons, numerous ongoing studies deal with their encapsulation into various delivery systems to maximize their therapeutic efficacy. One of these systems can also be crystals of nontoxic metal-organic frameworks (MOFs). In this work, we studied incorporation of a bioactive ruthenium(III) complex (RuC) inside MOFs derived from γ-cyclodextrin (γ-CD) and biocompatible potassium ions, forming CD-MOF-1. Viability studies in vitro were carried out using spheroids of human hepatoblastoma cell line HepG2. These studies revealed that the RuC-CD-MOF-1 system provides effective cancer cell suppression through slow gradual release over a longer period (>10 days) while reducing acute cytotoxic effects associated with naked RuC.

In this work, the substitution of copper in NiFe layered double hydroxide (LDH) was utilized to improve the sluggish kinetics of the water oxidation process. The simple in situ hydrothermal method was used to introduce copper into the NiFe LDH structure. All of the prepared catalysts displayed a sheet-like morphology, with the optimized NiCuFe LDH sample exhibiting a BET specific surface area of 117.5 m2 g-1. The optimized Cu-substituted LDH exhibited a superior performance in the alkaline water splitting process by requiring a lower overpotential of 230 mV to attain a current density of 10 mA cm-2, accompanied by a low Tafel constant of 47.7 mV dec-1, by outperforming the pristine NiFe LDH. The electronic structure modification of NiFe LDH by Cu atoms favors the OER process, which is verified by the density functional theory (DFT). Further, the optimized electrode was utilized in real-world conditions of the saline-alkaline electrolyte for water splitting, necessitating a minimal overpotential of 247.5 mV to oxidize water, and the electrode demonstrated long-term stability.
