However, for effective use in this context, these materials must be stable under ionizing radiation conditions. While previous studies have explored variations in metal node identities, topologies, and linker types, this study focuses on maintaining consistent metal and linker components to identify structural features that enhance radiation stability. We investigated the radiation resistance of three thorium-terephthalate hybrid materials─Th(BDC)2(DMF)2 (1,4-benzenedicarboxylic acid, dimethylformamide), Th(BDC)2, and Th-UiO-66─irradiated with He-ions up to a dose of 227 MGy. Structural stability was assessed through powder X-ray diffraction (PXRD), diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS), and density functional theory (DFT) calculations. The radiation stability thresholds were identified for Th(BDC)2(DMF)2 and Th-UiO-66, with Th(BDC)2 demonstrating exceptional stability even at the highest radiation dose. The observed stability trend is Th(BDC)2 > Th(BDC)2(DMF)2 > Th-UiO-66. Notably, the inclusion of DMF in Th(BDC)2(DMF)2 enhanced its radiation tolerance, likely due to DMF acting as a sacrificial ligand, preserving linker integrity at higher doses. Additionally, more unique node–linker connections and shorter interligand distances contributed to the improved radiolytic stability of these materials.","PeriodicalId":40,"journal":{"name":"Inorganic Chemistry","volume":"235 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143866413","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}

Theoretical calculations on square-planar tetradentate Pt(II) complexes show that deuteration exerts no electronic effects because deuterium has the same number of electrons as hydrogen. Consequently, the equilibrium structures (ground/excited states), frontier molecular orbital (FMO) distributions and energy levels, natural transition orbitals (NTOs), and spin–orbital coupling (SOC) remain unchanged. Deuteration-doubled mass lowers vibrational frequencies, reducing vibrational energy levels and zero-point energy (ZPE) by about 2.08 kcal/mol per deuteration, while slightly affecting the 0–0 transition energy (E0–0) and reorganization energy. Frequency reduction suppresses nonradiative decay rates (knr), boosting photoluminescence quantum yield (PLQY). Analyses of Huang–Rhys factors (S) and Franck–Condon factors (FC) show significant changes in mid-to-high-frequency vibrational coupling of particle and hole. Altered vibrational wave functions enhance the Herzberg–Teller (HT) transition dipole moment, affecting radiative decay rates (kr). Selective deuteration of the Cz ring effectively increases kr, suppresses knr, and modulates the fine structure of the spectrum, comparable to perdeuteration. C–D bond chemical degradation rate is about 3.94 times slower than C–H, further improving stability. These results establish a framework for optimizing emitters and extending OLED operating lifetimes.","PeriodicalId":40,"journal":{"name":"Inorganic Chemistry","volume":"10 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143872379","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 construct a two-dimensional (2D) S-scheme heterojunction through interfacial coupling of S-vacancy-rich ZnIn2S4 (SV-ZIS) with Bi2WO6 (BWO) nanosheets via an in situ growth method. Band alignment engineering establishes a giant built-in electric field at the Bi2WO6/SV-ZIS interface, which drives directional S-scheme charge transfer, leaving the photogenerated electrons and holes with the highest redox potentials accumulated on BWO and SV-ZIS, respectively, for O2 reduction and H2O oxidation. This spatial separation mechanism enhances both electron–hole pair dissociation efficiency (validated by transient photocurrent analysis) and preserves strong redox potentials (reflected in free-radical capturing experiments). The 2D/2D architecture further amplifies interfacial charge migration through atomic-level contact, leading to an efficient H2O2 production rate of 822 μmol L–1 h–1 in pure water.

MD simulations using tetrabutylammonium as counterion (TBA+) and Zr-hydroxo-aqua [W5O18Zr(OH)(H2O)]3– anions (W5Zr) indicate that these anions do not form permanent noncovalent contacts, but the interaction is directional occurring preferentially through Zr···Zr moiety contacts. In biphasic chloroform/water systems, the hydrophobic TBA+ countercations accumulate at the interface, creating a positively charged layer that attracts W5Zr anions. At the layer of TBAs, the W5Zr anions sit with hydrophilic Zr-aqua-hydroxo moiety pointing toward the bulk aqueous solution, favoring the frequency of W5Zr···W5Zr and Zr···Zr contacts further increased due to the local concentration. Detailed analysis of W5Zr···W5Zr contacts in bulk solution revealed that interactions are driven by intercluster hydrogen bonding between the two Zr-aqua-hydroxo moieties. Finally, potential of mean force (PMF) simulations are performed to evaluate the free-energy change when two W5Zr anions approach each other in solution, showing that the free-energy penalty is low (2–3 kcal·mol–1) and can be easily overcome at ambient temperature.","PeriodicalId":40,"journal":{"name":"Inorganic Chemistry","volume":"51 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143866415","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}

Such an evolution can significantly enhance the near-infrared (NIR) emission properties of Cr3+-doped phosphors. Herein, we present, to the best of our knowledge, the first observation of lithiation-induced continuous structural phase evolution in ZnTa2O6 phosphors, driven by Li+ incorporation. This evolution proceeds systematically from orthorhombic ZnTa2O6 (Pbcn) to tetragonal ZnTa2O6 (P42/mnm) and ultimately to trigonal (Li0.5Zn0.5)TaO3 (R3c) as the Li+ content increases. When doped with Cr3+, the NIR emission peak exhibits a progressive blue shift, moving from 949 to 885 nm and eventually to 862 nm, in tandem with the phase evolution. This phase evolution also yields significant enhancements in photoluminescent intensity, internal quantum yield (IQY), and photoluminescence thermal stability. Our findings establish a new paradigm for designing highly efficient ultra-broadband NIR phosphors and offer a foundation for developing tantalate-based materials with versatile functionalities, including improved dielectric properties.","PeriodicalId":40,"journal":{"name":"Inorganic Chemistry","volume":"108 3 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143866463","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}

Mn3+ preferentially occupies the octahedral site. This substitution has a strong impact on the magnetic properties as the magnetic ordering temperature, TN, is suppressed from 730 K for x = 0.0 to 465 K for x = 0.5 and the magnetic structure changes from Gx (x = 0.0) to Gy (x = 0.5–1.00). In this study, the compositions x = 0.10 and 0.25 are investigated using single-crystal X-ray and neutron diffraction methods. It is found that TN decreases linearly from x = 0.0 to x = 0.5, with values of 584(2)K for x = 0.25 and 684(2)K for x = 0.1. This behavior is rationalized in terms of a competition between antiferromagnetic and ferromagnetic exchange pathways in the perovskite layers involving Fe3+–Fe3+ and Fe3+–Mn3+ interactions. Profound changes in the magnetic anisotropy also occur as for both x = 0.25 and x = 0.1, the magnetic structure is neither Gx or Gy, but the moments lie between the a and b axes over nearly the entire temperature range. It has been shown that enhanced dielectric parameters are associated with another brownmillerite oxide, Ca2FeCoO5, in which nonaxial magnetic anisotropy is found within a narrow temperature range, 120–250 K. In the materials prepared in this study, this behavior should be evident at ambient temperature and over a wide temperature range.","PeriodicalId":40,"journal":{"name":"Inorganic Chemistry","volume":"5 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143866461","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}
