However, their synthesis is challenging. In this work a straightforward approach for generating unsymmetric 1,1'-ferrocene derivatives is described and applied to the synthesis of a multifunctional Fc therapeutic agent. Central to these developments is a new synthetic intermediate, Hydroxyl-Fc-Alkyne, featuring orthogonal linking functionalities: a propargyl ether for \"click\" chemistry, and a hydroxymethyl group enabling a variety of linking strategies. This intermediate facilitated the synthesis of a trifunctional anticancer candidate (Chl-Fc-Bio) combining Chlorambucil (Chl, chemotherapeutic), Fc (redox-active), and biotin (Bio, targeting). In vitro studies of growth inhibition were conducted on Chl-Fc-Bio, and a series of control molecules with systematic absences of one or two of the three molecular components, using both conventional cytotoxicity testing against MCF-7 breast cancer cells, and via the NCI-60 human tumor cell-line screen. Comparisons within this group of molecules, and with known therapeutics, revealed that Chl-Fc-Bio exhibits activity consistent with the combined effects of Chlorambucil's DNA alkylating properties and generation of reactive oxygen species by Fc. Stability studies of Chl-Fc-Bio showed pH-dependent ester cleavage, suggesting the potential for selective drug release in acidic tumor microenvironments. DFT calculations provided insights into the conformational properties of Chl-Fc-Bio, indicating conformational limitations on targeting by the biotin functionality. Direct ROS measurements confirmed enhanced ROS generation by the Fc group, consistent with its electrochemical potential. Overall, this work demonstrates an efficient and accessible method for constructing complex Fcbased molecules, with potential applications in the development of multifunctional drug candidates.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"20 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149359998","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 series of mono-and heterometallic 2,2-diethylmalonate-based coordination polymers, {[Ln2(Et2mal)2(phen)2(H2O)3(NO3)](NO3)(H2O)}n (Ln(III) = Tb, Eu, Gd), and investigate their structural, photophysical, and thermometric properties. Single-crystal X-ray diffraction reveals two crystallographically distinct lanthanide coordination environments, which are reflected in the luminescence properties. Steady-state and time-resolved spectroscopy, together with diffuse reflectance measurements, indicate that the excited-state relaxation involves ligand-centered states, Tb3+→Eu3+ energy transfer, and an additional charge-transfer excited state. The relative contributions of these pathways strongly depend on temperature and Eu3+ concentration, producing a dual thermometric mechanism in which low-temperature spectral changes are complemented by conventional thermally activated energy transfer at higher temperatures. The heterometallic compounds operate as ratiometric molecular thermometers over an exceptionally broad temperature range of 4-400 K. The best-performing composition Tb98Eu2 exhibits a maximum relative sensitivity of 6.1 % K-1 and a Sensitivity-Range integral of 745 %, placing it among the highest-performing molecular lanthanide thermometers reported to date.

Here, we investigate the rotational dynamics of terephthalate linkers in UiO-66(Zr) upon adsorption of n-butane and isobutane using variable-temperature 2H NMR spectroscopy across both hydroxylated and dehydroxylated forms of the framework. We demonstrate that while the fundamental π-flip motional geometry of the linkers remains unchanged, the presence of guests reduces the flipping rate by 1-2 orders of magnitude, with n-butane exerting a substantially stronger hindering effect than its branched isomer. Remarkably, adsorption of isobutane in dehydroxylated UiO-66 decreases the activation barrier for linker flipping from 30.3 to 20.4 kJ mol⁻¹, an unexpected phenomenon attributed to electronic perturbation of the inorganic node by guest coordination. Conversely, n-butane in hydroxylated UiO-66 increases the barrier to 26 kJ mol⁻¹, confirming specific interactions with framework OH groups.Furthermore, the width of the rate distribution narrows significantly upon adsorption (σ = 1.5-2 vs. 5 for guest-free material), indicating that adsorbed molecules mitigate the structural heterogeneity arising from intrinsic defects. We show that linker dynamics is a sensitive probe of guest-host interactions, provides insight to the molecular mechanism of butane isomers diffusivity and separation selectivity within the UiO-66 MOF and suggests new design principles for tuning MOF flexibility in separation applications.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"10 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149358820","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}

While the synergy between metal and phosphorus sites optimizes binding energetics for hydrogen intermediates, it remains challenging to achieve precise control over the extent of phosphorization that exerts an impact on the composition and microstructure of phosphides and thereby their electrocatalytic performance. Herein, we introduce a dealloying-assisted strategy to prepare a composite NiCo alloy precursor functionalized with a thin layer of NiCo hydroxide, which promotes the formation of phosphorus-rich NiCo phosphide (NiCoP) electrode during the subsequent phosphorization. The resultant NiCoP electrode demonstrates high catalytic activity and outstanding long-term stability, requiring an overpotential of 190 mV to achieve 500 mA cm−2 in 1 M KOH, with a low degradation rate of 0.23 mV h−1 for 350 h operation. Furthermore, an anion exchange membrane water electrolyzer constructed by pairing the NiCoP cathode with NiFe-based anode exhibits considerable device performance. This work provides a facile dealloying strategy for the in-situ formation of a hydroxide layer on metal alloy, and underscores the importance of precursor engineering in phosphorization control to enhance water splitting electrocatalysis.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"13 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149358927","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 ordered substitution occurs exclusively at the Si2 and N1 sites of the [Si2N4] tetrahedra, as supported by SCXRD refinements and DFT-calculated substitution formation energies. These crystals maintain a short UV cut-off edge at 240 nm, with only a marginal redshift upon [AlO] substitution. The orientationally ordered [AlN3O] tetrahedra induce a more than twofold anisotropic enhancement of birefringence. An SHG intensity exceeding 1.5 × KDP was observed, owing to enhanced local structural distortion and tetrahedral-composition-induced polarization with increasing [AlO] content.

Planar-chiral ferrocenes are privileged scaffolds in asymmetric catalysis, yet access to modular, 1,1′-differentiated enantiopure derivatives remains limited. Existing routes rely on multi-step sequences, often involving auxiliary-controlled lithiations, which restrict substitution diversity and efficiency. We present a coordination-controlled lithiation sequence exploiting the dual reactivity of a dimethylmethoxysilyl-substituted (aminomethyl)ferrocene. Depending on the lithium alkyl reagent, either selective 1′-deprotonation or methoxy substitution occurs, thus flipping a reactivity switch that enables a subsequent second ortho-lithiation. Combined NMR spectroscopy, X-ray crystallography, and DFT studies reveal cooperative amino/methoxy coordination as the origin of the observed 1′-regioselectivity. This mechanistically guided, one-pot protocol provides the first concise route to planar-chiral 1,1′-unsymmetrical ferrocenes, including N,P-, N,S-, N,O,S- and N,P,S-functionalized derivatives.

Here, we employ the recently discovered family of layered monophosphate tungsten bronzes (L-MPTB) as a model platform to uncover the fundamental principles governing solvent-coupled multivalent intercalation. By combining in situ powder X-ray diffraction, electrochemical quartz crystal microbalance (EQCM) measurements, quantitative charge analysis, and ab initio calculations, we identify two distinct potential-dependent intercalation regimes separated by a transition near −0.7 V vs. Ag/AgCl (3 M KCl). EQCM measurements reveal that this transition coincides with a switch in the intercalating species from hydrated hydronium H3O+(H2O) to di-hydrated barium Ba2+(H2O)2. Strikingly, the intercalation capacity is dictated by the redox limit of the host rather than by saturation of the crystallographically available sites. In situ diffraction uncovers an anisotropic lattice response to the ion uptake, while density functional theory calculations and structural analysis identify two cuboctahedral sites (M1 and M3) as the energetically preferred positions for multivalent guests. Together, these results establish a transferable framework connecting site energetics, hydration dynamics, and redox limits, providing mechanistic design guidelines for solvent-coupled multivalent intercalation hosts beyond this material family.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"1 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149305203","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, defect-rich Bi/BiOI hierarchical nanoflowers were constructed through a citric-acid-assisted one-step solvothermal strategy to regulate morphology, surface defect states, and charge-carrier behavior. Citric acid coordinated with Bi3+ ions and modulated the nucleation and subsequent growth of BiOI, thereby suppressing compact aggregation and promoting the formation of loosely assembled nanoflowers. Under ethylene glycol-mediated solvothermal conditions, citric acid addition also promoted the formation of oxygen-vacancy-related defects and metallic Bi. Together with the loosely assembled morphology, these features contributed to improved accessibility of reaction sites and enhanced charge separation and transport. The optimized BOI-C90 photocatalyst achieved removal efficiencies of 99.08%, 85.8%, and 96.8% for RhB, tetracycline, and Cr(VI), respectively, under visible-light irradiation. The corresponding apparent rate constants were 0.303, 0.329, and 0.174 min-1, representing 6, 4.57, and 2.26-fold enhancements over pristine BiOI. Mechanistic investigations revealed that organic pollutant degradation involved surface enrichment, direct hole oxidation, and ·O₂⁻-mediated reactions, while Cr(VI) removal proceeded through photogenerated-electron-mediated reduction. These results demonstrate that citric acid can couple morphology regulation with defect modulation, providing a simple route for constructing BiOI-based photocatalysts for the removal of both organic pollutants and Cr(VI) from water.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"13 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149305200","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}
