In this study, we report the development of a geometrically programmable core-shell catalyst (In2O3@Cu2O) fabricated via spray pyrolysis, in which the In2O3 core size precisely controls strain effects, interfacial electronic properties, and spatial confinement. The optimized In2O3@Cu2O catalyst exhibits near-unity Faradaic efficiency for CO (99%) across a broad current density range of 50-200 mA cm-2, while effectively suppressing both the hydrogen evolution reaction (HER) and C-C coupling. In situ spectroscopic analysis confirms the absence of C2 reaction intermediates (*OCCOH) and reveals a strain-induced redshift in the *CO vibrational frequency (from 2090 to 2052 cm-1), indicating weakened adsorption strength. Core-size-dependent performance evaluations further illustrate that a balanced geometric configuration effectively blocks In2O3-mediated formate generation pathways while optimizing active site exposure. This synergistic integration of spatial confinement, electronic modulation, and strain engineering establishes a robust design principle for selective CO2-to-CO conversion, offering a scalable and rational strategy for catalyst development in industrial CO2RR applications.","PeriodicalId":40,"journal":{"name":"Inorganic Chemistry","volume":"46 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145189161","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}

Herein, we investigate the trap depth evolution mechanism in the CaS systems by employing a lanthanide-ion codoping strategy in calcium sulfide nanocrystals, achieving a gradient-controlled trap depth modulation from 0.644 to 1.090 eV through Sm3+-mediated defect engineering. Thermoluminescence analysis (TL) combined with density functional theory (DFT) calculations reveals that the intrinsic sulfur vacancies act as shallow traps, enabling a persistent luminescence exceeding 600 s. Furthermore, the synergistic interactions between Sm3+ dopants and sulfur vacancies drive the modulation of trap depth, achieving the restructuring of defect states through the controllable doping concentration. This strategy demonstrates remarkable photostimulated luminescence (PSL) performance corresponding to deep trap states (980 nm excitation, 1 W/cm2, 3800 s). The developed core-shell architecture integrates multiresponsive capabilities: the core (CaS:Eu, Sm) preserves an optimized trap hierarchy, while the spatially selective shell (CaS:Er) doping introduces Er3+-mediated green upconversion luminescence (UCL). This work provides a paradigm for programmable stimulus-responsive luminescent materials, significantly advancing dynamic anticounterfeiting technologies with on-demand optical response capabilities.","PeriodicalId":40,"journal":{"name":"Inorganic Chemistry","volume":"23 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145194551","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}

However, achieving large birefringence in infrared (IR) chalcogenides remains a huge challenge due to the weak anisotropic polarizabilities and imperfect arrangement of single-anion tetrahedra. Herein, two new SnII-based oxychalcogenides, Ba2SnIIGe3O8S and Ba3SnIIGe3O2S8, were designed and synthesized by introducing the \"linkers\" with lone-pair electrons in oxychalcogenides. In the structures, the heteroleptic functional building units, [Ge3O8S] and [Ge3O2S8], are linked by the Sn2+-based groups to form two-dimensional {[SnGe3O8S]4-}∞ layers and one-dimensional {[SnGe3O2S8]6-}∞ chains, respectively, which promotes the large birefringence of 0.168@1064 nm for Ba2SnIIGe3O8S and 0.225@1064 nm for Ba3SnIIGe3O2S8. Remarkably, Ba3SnIIGe3O2S8 features the largest birefringence at 1064 nm among the reported oxychalcogenides containing [GeOxS4-x] (x = 1, 2, and 3) groups. Ultraviolet-visible and near-infrared diffuse reflectance and IR spectra measurements show that they have large band gaps (2.65-3.62 eV) and broad IR transmission windows. These results demonstrate the potential application of Ba2SnIIGe3O8S and Ba3SnIIGe3O2S8 in the IR region as birefringent materials and provide an effective method for the synthesis of chalcogenides with large birefringence.","PeriodicalId":40,"journal":{"name":"Inorganic Chemistry","volume":"68 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145189164","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}

We present a solvent-free mechanochemical strategy to construct luminescent multinuclear clusters via a dynamic ligand fusion. Starting from the preorganized dinuclear complex (BPBI)2Cu2Br4 (BPBI = 1-benzyl-3-(2-pyridinylmethyl)-1H-benzoimidazol-3-ium), the in situ formation of cationic [6,5,5,6]-fused heterotetracyclic ligands is driven by the Cu(I)-mediated C-N coupling between imidazole carbene and pyridine groups under alkali-driven mechanochemical conditions (t-BuONa). This process is supposed to involve a N-heterocyclic carbene-copper intermediate that directs the assembly toward the 0D organic-inorganic multinuclear cluster (BBIIP)4Cu4Br8 (BBIIP = 6-benzyl-6H-benzo[4',5']imidazo[2',1':2,3]-imidazo[1,5-a]pyridin-11-ium), where the planar π-conjugated BBIIP+ cationic coordinate with the [Cu4Br8]4- cluster to strengthen Cu···Cu interactions and stabilize the lattice. Crystallographic and DFT analyses demonstrate that the cluster's rigid architecture contributes to its photophysical performance: a photoluminescence quantum yield of 93%, lifetime of 6.01 μs, and thermal stability up to 300 °C. Furthermore, the ligand-cation interactions enable stimuli-responsive dual-mode emissions, with reversible spectral shifts and intensity modulation upon thermal and solvent stimuli, a behavior rarely reported in Cu(I) halides. By integrating the solvent-free synthesis, cluster-based structural design, and stimuli-responsive behavior, this work provides a viable approach to multifunctional optical materials, as exemplified in anticounterfeiting and adaptive optoelectronic applications.","PeriodicalId":40,"journal":{"name":"Inorganic Chemistry","volume":"24 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145189440","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}

In this study, we designed a series of fluorinated benzyltriphenylphosphonium salts by varying the number and position of fluorine atoms on the benzyl group. Using these salts as organic cations, four manganese(II) organic-inorganic metal halides─(BzTPP)2MnBr4, (FBzTPP)2MnBr4, (3,4-2FTPP)2MnBr4, and (3,4,5-3FTPP)2MnBr4─were synthesized.

When combined with PVDF to form flexible films for X-ray imaging, a spatial resolution of 7.15 lp mm-1 was achieved. Notably, fluorine substitution significantly improved the water stability of both crystals and films, enabling clear underwater X-ray imaging.
