In contrast to the previously reported coordination polymers based on octahedral cyanide cluster complexes, the 1D polymer [{Ag2(dppm)2}{Mo6I8}(CN)6] (2) demonstrated an order of magnitude increase in the cluster-centred photoluminescence quantum yield (Φem) in the solid state at 300 K in comparison with the ionic salt 1. Moreover, 2 displays bright X-ray induced emission, which is two orders of magnitude more intense than that of 1 and is characterized by a light yield of 10800 photons/MeV. Therefore, 2 represents the first effective scintillating compound, which is based on octahedral molybdenum clusters. The polymer have exceptional thermal, photo- and hydrolytic stability and displays minimal degradation upon X-ray irradiation, retaining its emission intensity following exposure to an air-equivalent dose of 2·103 Gray. It should be noted that no compounds based on octahedral molybdenum clusters have been previously obtained that would remain stable when exposed to such radiation doses. The high light yield and exceptional stability of the compound have enabled us to use it to manufacture scintillation screens for X-ray visualisation. These screens have a spatial resolution of up to 9 line pairs/mm, representing the first example of a scintillation device based on octahedral metal clusters.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"4 7 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145059263","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 report a systematic investigation across the lanthanide series of macrocyclic complexes incorporating azobenzene-functionalized diaza-crown ether ligands. We show that subtle changes in ionic radius across the Ln3+ series dictate conformational preferences and modulate trans-to-cis photoisomerization efficiency under UV and visible light. Surprisingly, we uncover that the reverse cis-to-trans isomerization, which is here unresponsive to thermal or photonic stimuli, is uniquely triggered by contact with glass surfaces, revealing a previously overlooked route for controlling molecular photoswitching. Additionally, selected complexes display efficient visible and near-infrared emission leveraged for robust luminescent thermometric behaviour in the solid state, with tunable sensitivity linked to the lanthanide. These findings advance the field of light-driven supramolecular materials and demonstrate how careful molecular-level design of lanthanide–azobenzene assemblies enables control over photoswitching, luminescence and thermal sensing properties, highlighting glass-mediated re-isomerization as a novel phenomenon with implications for future photoresponsive materials.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"66 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145025647","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}

Defect engineering offers a promising pathway to address these limitations. Therefore, in this study, MnCdS catalysts enriched with Mn defects were successfully prepared through the strategy of introducing metal cation vacancies. The optimized catalyst achieves an exceptional hydrogen evolution rate of 43.54 mmol g−1 h−1, which is three times higher than that of pristine MnCdS, while maintaining high stability. This significant enhancement is attributed to ethylenediamine (En)-induced Mn vacancies, which simultaneously augment active sites for electron capture in the conduction band and significantly accelerate water dissociation kinetics. By precisely regulating metal cation defects, this work demonstrates a highly efficient and stable photocatalyst while establishing a viable defect-engineering paradigm for advancing photocatalytic hydrogen evolution.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"35 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145025646","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}

The resulting complexes contain thiolato ligands which enable a close linkage between heteroaryl chromophores and the catalytic center, thereby promoting efficient photocatalytic hydrogen evolution under visible light irradiation. These mimics incorporate a push-pull organic chromophore, consisting of triphenylamine and (bi)thiophene groups, designed to facilitate direct photoexcitation into a charge-separated state. Electrochemical properties were examined using cyclic voltammetry, and photophysical characteristics were determined by steady-state spectroscopy and nanosecond-transient absorption supported by (TD-)DFT simulations. Whilst both catalytically active species revealed the formation of charge-separated states, directly upon excitation, fast deactivation due to relaxation into low-lying ferrocene-located states prevents the formation of long-living excited states in the ferrocene-linked dyad which explains the reduced activity for hydrogen generation of the dyad containing the ferrocene moiety compared to phenyl one.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"14 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145025644","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, a novel subgrid cage confinement engineering strategy was proposed, achieving ultra-efficient near-infrared (NIR) Cr3+–Ln3+ (Ln = Yb, Nd, Er) co-doped phosphors. The bilayer cage architecture of GdAl1.5Ga1.5(BO3)4 precisely confines Ln3+ at the central Gd3+ sites, while providing octahedral lattice positions for Cr3+ substitution within the Al/GaO6 framework. This unique confinement constrains Cr3+–Ln3+ separation to the optimal 3.67 Å while increasing the Ln3+–Ln3+ distance to 5.92 Å, enabling highly efficient Cr3+–Ln3+ energy transfer (ηETE: 61% for Yb3+, 82% for Nd3+, 46% for Er3+) and suppressing energy losses between neighbouring Ln3+ ions. Consequently, the Cr3+–Yb3+ co-doped system achieved a high photoluminescence quantum yield of 86% and retained 94% of its intensity even at 423 K, demonstrating exceptional thermal stability. The fabricated NIR phosphor-converted light-emitting diodes delivered a NIR output power of 127 mW with a photoelectric efficiency of 13% under a 300 mA operating current. These capabilities enabled high-contrast biological imaging applications, such as vein visualization and non-destructive testing, as validated by prototype demonstrations.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"16 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145025645","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, the high dissolution tendency of iron components may lead to irreversible loss of active sites, thereby compromising the long-term stability of the catalytic system. Herein, we successfully constructed an Fe/Ce doped Ni3S2/NiS heterostructure (denoted as FeOOH, Ce-Ni3S2/NiS) on nickel foam substrates through a combined hydrothermal sulfidation and electrochemical activation approach. By establishing a dynamic dissolution-adsorption equilibrium between Fe3+ in the electrolyte and the surface FeOOH layer, it effectively mitigated the loss of active sites. Simultaneously, the constructed Fe-Ce dual-active sites further stabilized the catalytic interface through synergistic effects. OER performance tests demonstrated that the catalyst required 266 mV overpotential to achieve 100 mA cm-2, with significantly improved Tafel slope (27.35 mV dec-1) and charge transfer resistance (1.161 Ω) compared to control samples. Remarkably, the catalyst maintained stable operation for 100 hours at an ultrahigh current density of 2.0 A cm-2. In addition, the anion-exchange membrane (AEM) electrolyzer (FeOOH, Ce-Ni3S2/NiS//Pt) was operated continuously for 100 hours at 1000 mA cm-2. This study proposes an electrolyte-mediated dynamic interface regulation strategy, providing new design principles for developing industrial water electrolysis catalysts with both high activity and exceptional stability.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"69 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145017191","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}
