Herein, we synthesized a single-component organic small molecule, methyl 4-((5-(thiophen-2-yl)-2H-tetrazol-2-yl)methyl)benzoate (MTTB), a thiophene-tetrazole derivative designed to exploit S•••N σ-hole interactions for directing polar assembly. Single-crystal X-ray diffraction reveals that MTTB crystallizes in the polar space group Pn, with directional S•••N contacts that template the non-centrosymmetric arrangement. The crystal delivers an SHG intensity 7.7-times that of KDP and a piezoelectric coefficient (d33) of 9 pC/N, while also retaining solid-state fluorescence. Density functional theory calculations reveal a HOMO-LUMO gap of 4.55 eV, along with the dipole moment and elastic moduli, providing insight into the electronic and mechanical origins of the observed SHG and piezoelectric responses. This work demonstrates that σ-hole engineering offers a viable strategy for integrating strong SHG, piezoelectricity, and fluorescence within a single-component organic crystal, suggesting a promising direction for the design of multifunctional polar organic materials.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"20 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149067375","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, the intrinsic microporosity of conventional bulk MOFs significantly restricts molecular diffusion pathways and limits accessibility to active sites. Therefore, converting bulk MOFs into hierarchical nanostructures has emerged as an effective strategy to address this issue. Herein, we propose a radical-driven reduction and protonation (RDRP) strategy. This approach employs photogenerated cyclohexyl radicals from 1-hydroxycyclohexyl phenyl ketone (UV-184) to treat two Cu(II)-based MOFs, successfully constructing hierarchical Cu(I)-MOFs with cubic (PC-I-R) and tubular (PC-II-R) architectures through radical-driven reduction and H⁺-dominated protonation. Notably, this transformation not only preserves the initial crystal morphology, but also maintains the monodentate coordination structure between copper ions and carboxylate groups. Density functional theory (DFT) calculations reveal that the uncoordinated carboxyl oxygen atoms act as Lewis basic sites, capable of accepting protons from the substrate's amino group. This enables PC-II-R to exhibit excellent catalytic performance in the reaction between propargylic amines and CO 2 under solvent-free and cocatalyst-free conditions. A turnover frequency (TOF) as high as 186 h -1 surpasses nearly all noble metal catalysts. The proposed RDRP strategy not only provides an innovative approach for nanostructuring of bulk MOFs but also sets a precedent for catalytic structures with multiple active sites.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"53 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149067440","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}

Combined spectroscopic investigations and theoretical calculations reveal that interfacial electronic reconstruction induces an S-scheme charge-transfer pathway, enabling efficient separation of photogenerated carriers while preserving strong redox potentials. Furthermore, in situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) coupled with density functional theory (DFT) calculations elucidates the CO2 reduction mechanism via a sequential *CO2 → *COOH → *CO pathway, with *COOH formation identified as the rate-determining step.

Nevertheless, borataalkene lanthanide complexes are significantly underdeveloped to date, which presumably can be attributed to the mismatch between soft π(B=C) donor and hard lanthanide ions. We herein illustrate several tethered borataalkene cerium complexes. Treatment of cerium diylide 1 with excess BEt3 generated complex 2, featuring a 6-membered NBCPCSi ring. Subsequent reactions between 2 and excess KC8 lead to dearylation and ortho-metalation, affording complex [3•K2(Et2O)3]2. Control experiments imply that dearylation likely happened prior to ortho-metalation in the formation of complex [3•K2(Et2O)3]2, as suggested by the isolation of complex 4•K(Et2O)2. In these complexes, the atomic distances between B and C range from 1.461(14)-1.517(16) Å, demonstrating the presence of borataalkene moieties. Quantum chemical calculations elucidate their electronic structures, revealing the η2-B,C-cerium interactions are predominately electrostatic in nature with distinct ligand-to-metal π donations and without significant π backbonding contributions. These findings may open an avenue to other borataalkene f-block complexes and novel catalytic transformations mediated by them.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"221 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149019754","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 apply the topology-symmetry approach of Dornberger-Schiff's order-disorder (OD) theory, combined with topological analysis of underlying nets, to systematically investigate the only practically used deep-ultraviolet (DUV) NLO crystal KBe2BO3F2 (KBBF) and related compounds. The local symmetry of KBBF-type layers and interlayer spaces is characterized, and the maximum degree of order (MDO) polytypes for KBBF, as well as for KBBF-like family Pb2BO3X (X = Cl, Br, I), are described using symmetry groupoids. Topological analysis shows that KBBF and Pb2BO3X structures possess different topological types, despite identical local layer symmetries. Guided by these results, we designed two novel KBBF polytypes with the Pb2BO3X topology of underlying net, and confirmed their thermodynamic stability by first-principles calculations. The designed KBBF-P321 phase exhibits significantly enhanced second harmonic generation (d22 = 0.58 pm/V compared to 0.47 pm/V for KBBF-R32) due to optimal alignment of [BO3] anionic groups in adjacent layers.

Yet practical routes to reversibly manipulate altermagnetic states remain limited and are dominated by structural or external-field modulation. Here, we introduce a chemical molecular-switch strategy that leverages tautomerism in organic linkers to reversibly control spin states in two-dimensional metal-organic framework (2D MOF). Using a Ni-based 2D frameworks as a representative system, we demonstrate a reversible transition between a nonmagnetic phase (Ni-L1) and an altermagnetic phase (Ni-L2) driven by solvent-assisted lactim-lactam proton transfer, with computed barriers of 0.30 eV (forward) and 0.43 eV (reverse). The altermagnetic state exhibits ligand-centered moments of ~ 0.50 µB and a characteristic spin-split electronic structure with band splitting extending across nearly the entire Brillouin zone. Symmetry analysis attributes this unusually persistent splitting to the reduced local (molecular) symmetry of the lactam linker, which removes mirror-related spin-degeneracy constraints present in higher-symmetry analogues. These results establish tautomerization as a chemically reversible handle for altermagnetic phase control in reticular materials and highlight molecular-scale symmetry as a decisive design parameter for reconfigurable altermagnetic electronics.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"47 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149019679","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}
