Here, we report a novel layered quaternary compound, Bi18O21.6Se1.8Cl7.2, which features three different anionic sublattices. Bi18O21.6Se1.8Cl7.2 consists of [Bi6O9.6Cl6] and [Bi12O12Se1.8Cl1.2] slabs that stack along the c axis alternatively. Comprehensive physical properties and electronic properties of Bi18O21.6Se1.8Cl7.2 single crystals reveal semiconducting behavior with an indirect band gap of ∼1.51 eV and the dominant electron-type carriers. Notably, Bi18O21.6Se1.8Cl7.2 exhibits exceptionally low c-axial thermal conductivity κc (∼0.261-0.307 W m-1 K-1) at room temperature, significantly expanding the phase space of the ultralow-thermal-conductivity Bi-O-Se-Cl system. Our findings highlight that the strategic combination of distinct two-dimensional building blocks with varied structural and anionic coordination environments offers an effective approach for designing new layered materials with tunable physical properties.","PeriodicalId":40,"journal":{"name":"Inorganic Chemistry","volume":"653 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144520905","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}

The metallorectangles were meticulously characterized through IR, NMR, UV-vis absorption and emission spectroscopy, elemental analyses, FESEM, and electrospray ionization mass spectrometry. The rectangular structural feature of metallacyclophane 3 was theoretically rationalized using DFT calculations, and its theoretical and experimental IR spectra were coherent. Furthermore, the metallacyclophanes exhibited modest anticancer activities against breast cancer (MDA-MB-231) and lung cancer (A549) cells. Additionally, the binding studies of metallorectangle 1 with triphenylene and pyrene as organic guests were performed using UV-vis absorption and emission spectroscopy, indicating substantial binding with binding constants of 7.23 × 105 M-1 and 8.43 × 105 M-1, respectively. The host-guest binding was also confirmed using a 1H NMR titration experiment.

Here, the binding of nitric oxide (NO) to the models (hemoCD-P and hemoCD-I) was investigated. The introduction of NO gas into the hemoCD complexes formed stable ferric and ferrous NO adducts. UV-vis, electron paramagnetic resonance, and resonance Raman measurements revealed the presence of six-coordinate ferric complexes and five- and six-coordinate ferrous complexes. The reductive nitrosylation from Fe(III)NO to Fe(II)NO proceeded at high pH, and the reaction rate was dependent on the Fe(II/III) redox potentials of hemoCD-P and -I. In acidic solution, the ferric NO complexes were stably formed due to slow autoreduction. The binding constants of NO to ferric and ferrous complexes were determined to be 105-6 and 1011-12 M-1, respectively. The binding data were highly comparable to those for natural heme systems, and the data for other gases (CO, O2, HCN, and H2S) were integrated and discussed. We conclude that hemoCD was an effective aqueous heme model system that reproduced the gas-binding properties of native heme proteins in both the ferric and ferrous states.","PeriodicalId":40,"journal":{"name":"Inorganic Chemistry","volume":"19 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144520906","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}

Recent studies demonstrated that these traditional models are inadequate for the kinetic parametrization of redox couples exhibiting significant peak potential differences and adhere to a modified B-V (mB-V) model, wherein the condition of α + β = 1 is relaxed. Consequently, a simulation program has been developed using Python, and the existing equations have been revised to accommodate the mB-V model and are verified employing digital simulations. The accurate kinetic parameters obtained using the modified method for the Fe3+/Fe2+ couple are α = 0.38 ± 0.00, β = 0.38 ± 0.00, Ef0 = 0.47 ± 0.00 V, and k0 = (4.9 ± 0.2) × 10-5 cm/s. For the [UO2(CO3)3]4-/[UO2(CO3)3]5- couple, the parameters are α = 0.27 ± 0.00, β = 0.26 ± 0.00, Ef0 = -0.70 ± 0.00 V, and k0 = (3.2 ± 0.4) × 10-6 cm/s. It is strongly recommended to determine whether α + β = 1 or α + β ≠ 1 and subsequently apply the corresponding analytical equations to achieve accurate kinetic parametrization of irreversible couples.","PeriodicalId":40,"journal":{"name":"Inorganic Chemistry","volume":"19 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144520909","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}

The rapid advancement in portable water-splitting devices has stimulated significant research interest in rechargeable metal-air batteries and solar cells. However, the scarcity of cost-effective, multifunctional electrocatalysts continues to limit their wide application. Herein, we demonstrate a Ce and Co incorporated, tetraethylene glycol-linked tetraphenyl porphyrin-based covalent organic polymer (Ce-Co-TEGP) exhibiting superior and highly productive multifunctional electrocatalytic activity. The catalyst demonstrated excellent performance toward the OER, ORR, and HER. The O binding sites in tetraethylene glycol moieties aid in incorporating Ce into the system. The optimized Ce-Co-TEGP catalyst exhibited superior catalytic activity with low overpotentials (η10) (280 mV for OER and 170 mV for HER). Additionally, the electrocatalyst shows ORR activity with an onset potential of 0.924 V vs RHE and a limiting current density of -5.9 mA cm-2. The as-synthesized Ce-Co-TEGP catalyst has further exhibited potential as an air-cathode material in rechargeable metal-air batteries. The constructed device exhibited superior open-circuit voltage, increased capacity, and peak power density, along with outstanding discharge-charge performance and extended cycle life.","PeriodicalId":40,"journal":{"name":"Inorganic Chemistry","volume":"1 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144520907","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}
