Nevertheless, controllable structural regulation and integrated multifunction in a structural platform remains a great challenge. Herein, two pairs of Cu(I) halide family of (MOPPZ)2Cu2X6 and (MOPPZ)2Cu4X8 (MOPPZ = 1-(2-Methoxyphenyl)piperazine, X = Br, I) were successfully synthesized in the same halide system through elaborate crystal engineering strategy. The different anionic skeletons enable these cuprous halides to display multicolor broadband light emissions arising from self-trapped excitons (STEs). Systematic studies reveal that (MOPPZ)2Cu4X8 show lower emission energies and higher luminescence efficiency than (MOPPZ)2Cu2X6, owing to stronger Cu•••Cu interactions and electron-phonon coupling, respectively. Interestingly, these halides show intriguing reversible stimulus-response phase transitions with dynamic photoluminescence (PL) switching, endowing them with significant potential for high-level anticounterfeiting and information encryption-decryption. In addition, (MOPPZ)2Cu4I8 exhibits excellent radioluminescence performance with a high light yield of 34400 photons MeV -1 , low detection limit of 470 nGy s -1 , which is attributed to the synergistic effect of high photoluminescence quantum yield (PLQY = 95.5%) and heavy atom effect. A high spatial resolution of 18 lp mm -1 in X-ray imaging was achieved on flexible (MOPPZ)2Cu4I8 screen, demonstrating significant potential in practical X-ray imaging application. This work realizes the integrated reversible stimuli-responsive PL switching and high-efficiency Xray scintillation in 0D Cu(I)-based metal halide, offering new insights for development of multifunctional optoelectronic devices.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"87 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148980717","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite the promising ferroptosis-induction potential, conventional photodynamic therapy (PDT) is constrained by inefficient reactive oxygen species (ROS) generation and intracellular glutathione (GSH) scavenging. Herein, we report two H2S-responsive dinuclear iridium(III) complexes, IrSS-1 and IrSS-2, engineered to simultaneously localize in LDs, generate abundant ROS via dual-type (Type I/II) PDT mechanisms and deplete GSH through disulfide bond cleavage. These synergistic actions lead to pronounced LPO accumulation and potent ferroptosis. Notably, IrSS-2-mediated PDT further triggers immunogenic cell death (ICD) by promoting calreticulin exposure, high-mobility group box 1 (HMGB1) release, and ATP secretion. Transcriptomic profiling confirms significant rewiring of ferroptosis-associated and antitumor immunity pathways. In vivo studies demonstrate robust tumor suppression with minimal systemic toxicity. Our work presents a pioneering strategy integrating LD-targeted dual-type PDT and GSH depletion to achieve self-amplifying ferroptosis and ICD. It opens a new frontier in precision medicine by merging subcellular targeting, redox control, and immune engagement in one intelligent molecular platform.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"4 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148993838","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we report a facile radical addition reaction of Ce2@Ih-C80 with benzyl bromide. This reaction proceeds via cascade functionalization and surprisingly affords three products, rather than the typical single monoadduct: two monoadduct isomers (2a and 2b), each bearing one benzyl group, and one triadduct (3a) bearing three benzyl moieties. More importantly, the molecular structures of 2a, 2b, and 3a were unambiguously determined by single-crystal X-ray crystallography. Combining these unambiguous molecular structures with magnetic characterizations and theoretical calculations, we gain comprehensive insights into the sitedependent dynamic behaviors of metal-cage interactions and adaptive metal-metal bonds.

Here, we describe the synthesis of a series of DNA binding ruthenium(II) polypyridyl complexes (RPCs) containing the extended anthraquinone intercalating ligand qdppz (qdppz = naphtho[2,3-a]dipyrido[3,2-h:2‘,3‘-f]phenazine-5,18-dione) and methylated ancillary ligands. A modified ethidium bromide displacement assay indicated all complexes possess enhanced affinities for CC mismatch-containing duplexes over well-matched, with [Ru(5,5’ dmbpy)2(qdppz)]2+ (5,5’ dmbpy = 5,5'-dimethyl-2,2'-bipyridine) showing the broadest mismatch selectivity of the series. Mismatch binding was further supported by a novel quenching assay that exploits the previously unreported ability of Ru(qdppz) complexes to quench Cyanine 5.5-labelled DNA. In MTT assays using MMR-deficient DLD-1 and MMR-proficient DLD-1+Chr2 colorectal adenocarcinoma cells, [Ru(5,5′-dmbpy)2(qdppz)]2+ was the most active complex and exhibited lower IC50 values than cisplatin in both cell lines. However, the limited DNA damage observed was consistent with the absence of MMR-dependent selectivity, suggesting a mismatch-independent mechanism of cytotoxicity. Live-cell bioenergetics instead revealed an unexpected impact of [Ru(5,5’ dmbpy)2(qdppz)]2+ on mitochondrial respiration, including a decrease in basal respiration, ATP production, maximal respiration, and spare respiratory capacity. ICP-MS analysis of isolated mitochondria confirmed mitochondrial localisation and displacement of a mitochondrial DNA dye is consistent with mtDNA as a target. Combined with the absence of a cytotoxic response, this work provides a distinct biological activity for a substitutionally inert RPC that binds DNA by intercalation.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"1 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148993843","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unlike robust aluminosilicates, their Al-O-P linkages are susceptible to rapid structural collapse during conventional alkaline etching due to preferential phosphorus leaching and fatal stoichiometric imbalance. Herein, we resolve this dilemma via a neutral phosphorus-compensated dissolution-recrystallization strategy. By employing neutral triethyl phosphate (TEP) as a buffered phosphorus reservoir, this protocol decouples alkalinity maintenance from chemical nutrient supply. TEP’s slow hydrolysis kinetically matches the framework dissolution rate, facilitating immediate in-situ recrystallization of dissolved species into ordered frameworks. Using nanosized AlPO4-11 as a model, we demonstrate its transformation into single-crystalline hollow architectures with restored Al/P stoichiometry and high solid yields (>70%). The universality of this constructive remodeling mechanism is verified across AEL, AFI, AEI, and CHA topologies. Crucially, the resulting hierarchical SAPO-34 catalyst exhibits superior performance in the methanol-to-olefins (MTO) reaction, achieving a 2.7-fold lifetime extension with 86% light olefin selectivity. This enhanced stability stems from alleviating confinement-induced coking within the 8-membered ring cages, establishing a generalized paradigm for the structural engineering of chemically labile porous materials.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"1 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148980724","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we show that Hirshfeld Atom Refinement (HAR), which employs ab-initio electron-density-derived atomic form factors, allows quantitative modelling of co-existing LS and HS isomers as crystallographic disorder. Applying this method to four representative iron(II) SCO complexes -[Fe(phen)₂(SCN)₂], [Fe(pic)₃]Cl₂•EtOH, [Fe(PM-Bia)₂(NCS)₂] and [Fe(tpa)(SCN)₂]₂•MeOH -we refined temperature-dependent site-occupancy factors that correspond to the HS fraction. High-resolution data (in-house and synchrotron) reveal abrupt or gradual changes of the HS and LS-fractions. Reproducibility measurements across different crystals yield uncertainties ≤0.5 %, and the choice of hybrid DFT functional influences the occupancies only marginally. Even a two-step transition, observable for [Fe(tpa)(SCN)₂]₂•MeOH, is accurately described using a simple disorder model. Consequently, HAR-based disorder refinement provides a robust, quantitative crystallographic tool for probing spin-state superpositions in SCO materials.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"52 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148980725","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its practical sensing implementation still suffers from an inherent trade-off between analytical sensitivity and operational simplicity. Herein, we successfully fabricated the first ScIII–CeIII heterometallic bismuthotungstate H11Na14(NH4)8[Ce3(H2O)8Sc6(H2O)6W9O30(B-β-BiW9O33)6]∙78H2O (1) via a facile stepwise assembly strategy. Structural analysis reveals that the polyanion of 1 is constructed from six [B-β-BiW9O33]9– building blocks and an 18-nuclear ScIII–CeIII–WVI trimetallic [Ce3(H2O)8 Sc6(H2O)6W9O30]21+ core. Leveraging the unique multimetallic synergistic effect, 1 displays favorable peroxidase-like activity, which enables the efficient decomposition of H2O2 into hydroxyl radicals (·OH) and further oxidizes colorless 3,3',5,5'-tetramethylbenzidine (TMB) into blue oxidized TMB. Based on the mechanism that S2O32− scavenges ·OH to inhibit the oxidation of TMB, which causes the blue color to fade, we constructed a novel 1-based triple- modal colorimetric-photothermal-smartphone sensing platform for S2O32− detection. This platform demonstrates a linear response to S2O32− in the range of 0.05–60 μM, with corresponding detection limits of 0.0081±0.0006 μM (colorimetric), 0.0086±0.0008 μM (photothermal) and 0.0075±0.0005 μM (smartphone). Moreover, it displays outstanding selectivity, operational stability, and anti-interference capability. Satisfactory recoveries (93.5%–108.2%) in real environmental and food samples further validate its robustness and practical applicability.

Herein, we report a facile in-situ partial phosphorization strategy to construct an intimately contacted CoP-CoO heterostructure, in which a single CoP phase bears two functions: acting as the *NO2 hydrogenation site, and serving as the near-infrared (NIR) photothermal transducer. A spatially decoupled adsorption relay (SDAR) mechanism is established, wherein CoO preferentially deoxygenates NO3 -and the resulting *NO2 is thermodynamically relayed to adjacent CoP sites for hydrogenation. The intimate heterointerface drives electron transfer from CoO to CoP, facilitating intermediate relay. The NIR irradiation is concurrently converted into localized surface heat (~23°C rise, versus only ~2°C in the bulk electrolyte), accelerating the potential-insensitive steps and lowering interfacial charge-transfer resistance. The optimized CoP-CoO-10 achieves an NH3 Faradaic efficiency of 93.9% and a yield rate of 111.6 μmol h -1 cm -2 at -0.3 V vs. RHE under NIR irradiation, a 1.6-fold enhancement over dark conditions.
