Noncentrosymmetric crystallization, directional arrangement of dipoles and appropriate flipping barrier are all difficult problems in building ideal ferroelectric materials. In this article, a novel hybrid material TDMHACdCl3 (1, TDMHA+ is N-(tert-butyl)-N,N-dimethylhydroxylammonium) with ferroelectric property was successfully synthesized and characterized. A CH3/OH substitution strategy was employed to construct the hydrogen bond between the organic cation and the inorganic framework, deflecting the dipole moment direction of the cation. To minimize the energy of the crystal lattice, hydrogen bonds compete with the cation conformation, causing the cations to deviate from the optimal conformation, allowing the dipoles to be oriented in one direction. The crystal structure and quantum chemical calculations were thoroughly discussed to reveal the origin of the ferroelectric property in this work. We believe that our design will contribute to the discovery of more ferroelectric materials.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"70 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143654202","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, most zeolites growth involves intertwined classical and non-classical mechanisms, making it crucial to distinguish and modulate their contributions in original synthetic system. In this study, we provide a method to distinguish and directly quantity the contributions of classical and non-classical crystallization pathways in MFI zeolite synthesis, demonstrating that the dominant pathway can be shifted from non-classical to classical by varying the H2O/SiO2 and ethanol/SiO2 ratios. Our findings show that reducing H2O/SiO2 favors the non-classical pathway, while increasing ethanol/SiO2 promotes the classical mechanism. However, these changes have minimal effect on their crystallization sequences: the non-classical pathway predominates initially, but both pathways intertwine as crystallization progresses. Notably, the shift in crystallization pathway does not significantly affect the acidic properties of the zeolites but has a direct impact on their catalytic performance. The catalytic activity of the resulting ZSM-5 zeolites in furfuryl alcohol etherification correlates with the classical pathway contribution, with higher contributions leading to enhanced catalytic activity. This study provides new insights into the zeolite crystallization process, offering a valuable approach for optimizing synthesis conditions and improving catalyst performance.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"24 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143640184","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, two synergistic crystalline catalysts assembled with Wells-Dawson-type [P2W18O62]6- cluster and heterovalent Cu-complex were synthesized for benzylic C−H oxidation, with the formula of [Cu3ICu3II(μ2-OH)6(H2O)1.5(DTAB)3][H3P2W18O62]·18H2O (1), and [CuI2(DTAB)2]{[CuI2(μ3-Cl)][CuI4(μ3-Cl)](DTAB)4]}[P2W18O62]·9H2O (2) (DTAB = 1,4-di[4H-1,2,4-triazol-4-yl]-benzene). Compound 1 possesses 2-D copper-ligand cation layers composed of heterovalent [CuI3CuII3(μ2-OH)6]3+ chains, in which the protonated [H3P2W18O62]3- polyanions intercalate between them.

The heterovalent copper species and [P2W18O62]6- clusters within two compounds render them dual-site synergistic catalysts for exploring the roles of each component in the selective oxidation of benzyl C-H bond. Using the oxidation of diphenylmethane (DPM) as a model reaction, two synergistic catalysts displayed ca. 95% and 92% DPM conversion with &gt;98% benzophenone (BP) selectivity within 8h. Mechanism investigations revealed that both copper sites and polyanionic clusters as active centers corporately promoted the absorption and activation of t-BuOOH oxidant in the radical-mediated DPM oxidation reaction via coordination and hydrogen bonding interactions to generate active t-BuO• and •OH radicals, accelerating the oxidation of DPM and the formation of BP. Additionally, this kind of synergistic catalysts showcased excellent substrate compatibility and recoverability, as well as robust structural stability.

Herein, an efficient and thermally stable broadband NIR LaMgGa11O19:Cr3+,Yb3+ (LMG:Cr3+,Yb3+) phosphor has been successfully designed by [Cr3+-Yb3+] co-doping. The broadband emission phenomenon of LaMgGa11O19:Cr3+ was confirmed to be due to selective lattice occupancy of Cr3+ ions based on the analysis of crystal structures, crystal field calculations, and fluorescence lifetimes. The NIR emission spectra in the range of 1000-1200 nm were enriched by using the highly efficient energy transfer of Cr3+→Yb3+ ions and the detailed the energy transfer mechanism is discussed in detail. The prepared LMG:Cr3+,Yb3+ phosphors exhibit highly efficient ultra-broadband NIR emission from 650 to 1200 nm under 440 nm excitation with high internal and external quantum efficiencies of 94.2%/40.5% and excellent luminescence thermal stability of 89.3%@373 K. A NIR pc-LED prototype was fabricated by combining the optimized phosphor with a commercial 440 nm blue LED chip, providing 84.5 mW NIR output power at 350 mA driven current.
