The far-IR (FIR) region, namely below ~700 cm-1 is rarely considered except for “fingerprinting”, although metal-ligand vibrations of interest can occur in this spectral region. Electronic transitions in transition metal complexes would be considered to be at much higher energy, minimally in the near-IR region (above ~10 000 cm-1, wavelength of ~1000 nm). Yet in many cases of paramagnetic transition metal ion complexes, there are lower energy electronic transitions, between spin sublevels resulting from zero-field splitting (zfs), a phenomenon that is the consequence of spin-orbit coupling (SOC). Such transitions can be observed in the far-IR region and their identity confirmed and refined by application of an external magnetic field, hence far-infrared magnetospectroscopy (FIRMS). Spectroscopy of this type has been known for many years, but only recently has emerged as a crucial technique for understanding paramagnetic transition metal complexes with potential application in molecular magnetism and more broadly in quantum information science. Examples of mononuclear complexes of Ni2+, Co2+, and Fe2+, representing three different spin states (S = 1, 3/2, and 2, respectively), and a special case of S = 1/2 Ni+, are given in this Highlight to demonstrate the value of FIRMS in understanding electronic structure, particularly in cases of unusual geometry such as low coordination number (2- and 3-coordinate).","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"10 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148973501","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}

Co II ion shows remarkable advantages in intrinsically fast spin transition dynamics and high stimulus sensitivity of the SCO behavior, in contrast to traditional Fe II ion. However, to the best of our knowledge, intrinsic SCO in discrete multinuclear Co II circular helicates remains unexplored due to small enthalpy and entropy changes in high-spin (HS) and low-spin (LS) state transition. Herein, a family of quadruple and triple circular helicates was assembled from ditopic-tpy (tpy= 2,2':6',2''-terpyridine) ligands (L1, L2) and transition metal ions (Fe II , Co II ). Strikingly, discrete and nonstrained triple circular helicate 6 reveals rare thermally induced SCO of Co II centers (T1/2 ≈ 100 K), confirmed by single crystal X-ray diffraction (SC-XRD), electron paramagnetic resonance (EPR), and variable temperature magnetic susceptibility measurements. Additionally, it spontaneously resolves from a racemic mixture into ΔΔΔ or ΛΛΛ enantiopure entities during crystallization. Conversely, the highly strained Co II quadruple circular helicate 5 shows no SCO and crystallizes as a racemate. This work establishes an effective ligand skeleton engineering strategy to tailor SCO properties via intramolecular strain modulation, providing a new platform for the design of supramolecular magnetic switch materials.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"14 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148964387","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 rational design of advanced catalytic materials is crucial for enhancing the performance of artificial photosynthesis in CO2 reduction and achieving practical applications. Amongst the most promising materials for CO 2 capture and utilization, layered double hydroxides (LDHs) possess a unique two-dimensional layered structure, endowing them with excellent physical and chemical properties as energy materials. To address common limitations of conventional LDH photocatalystssuch as high recombination rates of photogenerated electron-hole pairs and low solar energy utilization efficiency-this review discusses strategies including morphology control, surface modification, compositing, and utilization of LDH precursors to improve the photocatalytic CO2 reduction performance of LDHs.

Using the Bi 3.25 La 0.75 Ti 3 O 12 (BLTZ) system fabricated via a sol-gel process as a prototype, we demonstrate that the incorporation of Zr thermodynamically induces the precipitation of a cubic Pyrochlore phase from the layered Aurivillius matrix. This strategy successfully constructs a unique \"nanocrystal-amorphous\" composite architecture, where nanocrystals of both phases are firmly embedded within a random amorphous network. This specific microstructural configuration triggers a significant synergistic enhancement mechanism: the retained Aurivillius nanocrystals ensure high polarization, the Pyrochlore phase effectively mitigates hysteresis loss, and the random amorphous network acts as a robust barrier to charge transport, substantially suppressing leakage current and elevating breakdown strength. Consequently, the film exhibits superior performance surpassing similar counterparts: even at a thickness of only 190~200 nm, it achieves an ultra-high breakdown strength (E b ) of 4.72 MV/cm, yielding a recoverable energy density of 165.3 J/cm 3 with an efficiency of 74%, alongside excellent fatigue resistance.

Herein, a sulfate-intercalated Cu-Al layered double hydroxide (LDH) is proposed as an artificial interphase that synergistically combines steric sieving with zincophilic coordination to regulate the Zn 2+ desolvation and deposition. The sub-nanometer interlayer galleries of LDH (3.7 Å) physically sieve hydrated [Zn(H 2 O) 6 ] 2+ ions to promote partial pre-desolvation and guide uniform ion flux, suppressing water-induced side reactions.Meanwhile, the confined SO 4 2-anions within the galleries act as zincophilic anchors to reconstruct the interfacial solvation configuration, accelerating desolvation kinetics while restricting SO 4 2-migration. As a result, the Cu-Al LDH interphase enables dendrite-free and highly reversible Zn deposition with significantly suppressed side reactions. The Cu-Al LDH@Zn anode delivers an ultralong cycling lifespan exceeding 2500 h with an average Coulombic efficiency of 99.8%, and the Cu-Al LDH@Zn//NVO full cell maintains 87% capacity retention after 1000 cycles at 3 A g -1 .

Herein, we propose a fluorination strategy to design red-emitting phosphors with non-concentration-quenching and anti-thermal-quenching properties. The as-synthesized α-BaEuBO3F2 exhibits an intense and concentration-quenching free red emission centered at 612 nm with a relatively high quantum efficiency of 78.8% under the optimal 393 nm blue light excitation. Impressively, this red-emitting α-BaEuBO3F2 phosphor demonstrates superior thermal stability in the elevated temperature range of 150–270 °C (maintaining >90% intensity), outperforming conventional red Y2O3:Eu3+ phosphors. In addition, the application of this red α-BaEuBO3F2 phosphor in a pc-WLED has been demonstrated, yielding warm white light with color coordinates at (0.3425, 0.3325), a color rendering index (CRI) of 82.49, and a correlated color temperature (CCT) of 5000 K.

However, neither ˙OH nor methyl radicals (˙CH3) could be detected from peroxynitrous acid using the electron spin resonance (ESR) spin trapping method with 5,5-dimethyl-1-pyrroline-N-oxide (DMPO) as the spin-trapping agent either in the absence or presence of dimethyl sulfoxide (DMSO). In this study, we chose 3-morpholinosydnonimine N-ethylcarbamide (SIN-1) to selectively produce peroxynitrous acid and found that when the well-known thiol antioxidant glutathione (GSH) was present, both ˙OH and secondary ˙CH3 (from DMSO) could be unequivocally detected from SIN-1. Further investigation revealed that the GSH-mediated generation of ˙OH and ˙CH3 was closely dependent not only on the production of superoxide anion radical (O2˙−) via thiyl radical formation during the oxidation reaction of GSH with SIN-1 but also on the spin-trapping agent DMPO. Analogous results were observed for several other sulfhydryl compounds (RSH) and spin-trapping agents. Interestingly, we found that ˙CH3 could also be produced from the typical O2˙−-generating systems (xanthine/xanthine oxidase and KO2/crown ether) with DMPO/DMSO. Taken together, the mechanism for ˙OH generation from SIN-1/DMPO/RSH was proposed: RSH could react with peroxynitrous acid generated from SIN-1 decomposition to produce a large amount of O2˙−via thiyl radical formation, which could be trapped by DMPO to form the unstable DMPO–OOH adduct that subsequently decomposed to yield ˙OH. This study discovered a unique ˙OH-generating pathway, which could not only better explain previous findings but also might have significant chemical, biomedical, and toxicological implications for future research on the interaction of sulfhydryl compounds and peroxynitrous acid, especially in the presence of spin trapping agents.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"39 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148957876","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}
