Boron cage hybrid supramolecular metal-organic frameworks (BSFs) are a subclass of anion-pillared MOFs (APMOFs). This type of materials are formed through the self-assembly of borane cage anions, metal cations and organic ligands. They possess dense arrays of anionic binding sites within the one-dimensional pores, which can interact selectively with hydrocarbon molecules via B–H⋯H–C dihydrogen bonds. Therefore, the design of BSFs with appropriate pore properties holds significant potential for achieving highly efficient hydrocarbon separation. However, the current research on BSFs is still in its infancy when compared to other types of APMOFs. Due to the weak coordination ability of borane anions, the directional assembly of BSFs remains challenging. This review article targets to provide an overview of the development history of BSFs, and introduce in detail their design strategies and synthesis methods. In addition, this review will elaborate on the characteristics of BSFs and discuss their gas separation performance. Finally, the current challenges faced by BSFs are summarized, and reasonable suggestions for the future design, development, and industrial application of BSFs are put forward.
硼笼杂化超分子金属有机骨架(BSFs)是阴离子柱型金属有机骨架(APMOFs)的一个亚类。这类材料是通过硼烷笼型阴离子、金属阳离子和有机配体的自组装形成的。它们在一维孔隙中具有密集的阴离子结合位点阵列,可以通过B-H⋯H-C二氢键选择性地与碳氢化合物分子相互作用。因此,设计具有适当孔隙特性的bsf对于实现高效碳氢化合物分离具有重要潜力。然而,与其他类型的APMOFs相比,目前对BSFs的研究还处于起步阶段。由于硼烷阴离子的配位能力较弱,bsf的定向组装仍然具有挑战性。本文综述了bsf的发展历史,详细介绍了bsf的设计策略和合成方法。此外,本文还阐述了流化床的特点,并对其气体分离性能进行了讨论。最后,总结了目前bsf面临的挑战,并对bsf未来的设计、开发和工业应用提出了合理的建议。

Four zinc borates, MNa9ZnB16O28(OH)4 (M = K, Rb, Cs; 13) and Na3ZnB5O10 (4), have been made under solvothermal conditions. Compounds 13 are isostructural and contain an unprecedented [B16O28(OH)4]12− cluster constructed from eight B3O3 rings sharing BO4 tetrahedra. The clusters further link with ZnO4 tetrahedra to form one-dimensional (1-D) chains, which further assemble into a 3D supramolecular framework through hydrogen bonds. 4 was made by raising the reaction temperature of 1 and features a porous-layer structure composed of [B4O9]6− clusters, BO3 units and ZnO4 tetrahedra. All compounds exhibit short deep ultraviolet (DUV) cutoff edges below 190 nm. Notably, 13 crystallize in the acentric space group I−4 and display second harmonic generation (SHG) responses of approximately 1.26, 1.30 and 1.32 times that of KH2PO4 (KDP), respectively, highlighting their potential as DUV nonlinear optical materials.
在溶剂热条件下制备了四种硼酸锌,MNa9ZnB16O28(OH)4 (M = K, Rb, Cs; 1−3)和Na3ZnB5O10(4)。化合物1 ~ 3是同结构的,含有一个前所未有的[B16O28(OH)4]12−簇,由8个共享BO4四面体的B3O3环构成。团簇进一步与ZnO4四面体连接形成一维(1-D)链,通过氢键进一步组装成三维超分子框架。4是通过提高1的反应温度制成的,具有由[B4O9]6−簇、BO3单元和ZnO4四面体组成的多孔层结构。所有化合物在190 nm以下均表现出较短的深紫外截止边。值得注意的是,1−3在非中心空间群I−4中结晶,并显示出二次谐波产生(SHG)响应,分别约为KH2PO4 (KDP)的1.26倍,1.30倍和1.32倍,突出了它们作为DUV非线性光学材料的潜力。

Nanofibers hold great promise as oxygen electrode materials in solid oxide cells (SOCs). However, conventional fabrication methods—such as slurry processing and high-temperature sintering—inevitably disrupt their delicate nano-architectures. Here, we propose an innovative self-assembly strategy mediated by current polarization to construct La0.6Sr0.4Co0.2Fe0.8O3δ-Gd0.1Ce0.9O2δ (LSCF-GDC) nanofiber composite film electrodes. This approach largely preserves the fibrous morphology while promoting coherent heterointerfaces, abundant active sites, and efficient electron/ion pathways. Benefiting from this tailored architecture, the electrode achieves a low polarization resistance of 0.117 Ω cm2 and a peak power density of 1.482 W cm−2 at 800 °C. Moreover, in CO2 electrolysis mode, it delivers an impressive current density of 2.30 A cm−2 at 1.8 V. These results establish nanofiber heterostructure films, enabled by current polarization assembly, as a powerful strategy to simultaneously enhance activity, durability, and mass transport, offering new opportunities for high-performance intermediate-temperature SOCs.
纳米纤维在固体氧化物电池(soc)中作为氧电极材料具有广阔的应用前景。然而,传统的制造方法——如浆液处理和高温烧结——不可避免地破坏了它们精致的纳米结构。在此,我们提出了一种创新的电流极化自组装策略,构建La0.6Sr0.4Co0.2Fe0.8O3−δ- gd0.1 ce0.9 o2−δ (LSCF-GDC)纳米纤维复合膜电极。这种方法在很大程度上保留了纤维形态,同时促进了相干异质界面、丰富的活性位点和高效的电子/离子通路。得益于这种定制的结构,该电极在800°C时实现了0.117 Ω cm2的低极化电阻和1.482 W cm−2的峰值功率密度。此外,在CO2电解模式下,它在1.8 V下提供了令人印象深刻的2.30 A cm - 2电流密度。这些结果建立了纳米纤维异质结构薄膜,通过电流极化组装,作为同时增强活性,耐久性和质量传输的强大策略,为高性能中温soc提供了新的机会。

Diatomic-site catalysts (DACs) have recently emerged as highly promising platforms for photocatalytic CO2 reduction, offering unique opportunities to control reaction thermodynamics and kinetics for selective C2+ product formation. By integrating two adjacent metal centers within well-defined architectures, DACs enable synergistic activation of CO2 and stabilization of key C–C coupling intermediates, surpassing the limitations of single-atom or bulk catalysts. This perspective highlights the recent advances in DAC synthesis strategies, characterization techniques, mechanistic insights into multi-carbon formation, and the fundamental reasons why DACs facilitate C–C bond formation with high selectivity. A critical discussion is presented on the mechanism of C2+ formation on these unique active sites. Furthermore, the role of defect engineering within the catalyst support or surrounding matrix in modulating the electronic structure and stability of DACs is thoroughly examined. Finally, this perspective outlines future research directions to further unlock the full potential of DACs for efficient and selective photocatalytic CO2 reduction to C2+ products.
硅藻位催化剂(DACs)最近成为光催化CO2还原的极具前景的平台,为控制选择性C2+产物形成的反应热力学和动力学提供了独特的机会。通过将两个相邻的金属中心整合在明确的结构中,dac能够协同激活CO2并稳定关键的C-C偶联中间体,从而超越了单原子或体催化剂的局限性。这一观点强调了DAC合成策略、表征技术、多碳形成机制的最新进展,以及DAC以高选择性促进C-C键形成的根本原因。对这些独特的活性位点上C2+的形成机制进行了批判性的讨论。此外,在催化剂载体或周围基质中的缺陷工程在调制dac的电子结构和稳定性中的作用进行了彻底的研究。最后,这一观点概述了未来的研究方向,以进一步释放dac在高效和选择性光催化CO2还原为C2+产物方面的全部潜力。

Coordination-directed synthesis has emerged as an effective and versatile approach for constructing mechanically interlocked molecules (MIMs). This field has long been dominated by Werner-type complexes featuring oxygen and/or nitrogen donors, whereas assemblies incorporating N-heterocyclic carbene (NHC) donors remain underexplored. This review provides a comprehensive overview of the rapidly developing field of MIMs constructed from poly-NHC-based building blocks. By highlighting representative recent examples, this review focuses on the pivotal role of NHC ligands and the robustness of metal-CNHC bond in the construction of metallosupramolecular interlocked structures. In addition, it summarizes contemporary strategies for achieving efficient assembly, analyzes defining structural attributes of the resulting architectures, and outlines current challenges and emerging opportunities for future developments in NHC-based MIMs.

Covalent organic frameworks (COFs), as a burgeoning type of porous material, have attracted significant attention due to their intriguing structural characteristics and customizable functionalities. Particularly, COFs that exhibit luminescent properties have garnered significant attention in fields like chemical sensing, biosensing, photocatalysis, optoelectronics applications and so on. This article systematically examines the synthetic strategies for luminescent covalent organic frameworks (LCOFs) and provides a comprehensive summary based on linkage-type classification. It further provides a comprehensive summary and emphasizes the broad and notable applications of LCOFs across multiple areas, such as luminescent applications, circularly polarized luminescence, fluorescent imaging, biomedicine, and chemical and biological sensing. Finally, the primary challenges and future directions of LCOFs concerning their synthetic method, structural design and optical properties are discussed. This review helps researchers quickly understand the current research status in this field, and points out the direction for subsequent related research work. It is expected to promote the further development and application expansion of LCOFs synthesis technology, which has important academic value.
共价有机框架(COFs)作为一种新兴的多孔材料,由于其有趣的结构特性和可定制的功能而引起了人们的广泛关注。特别是具有发光特性的COFs,在化学传感、生物传感、光催化、光电子等领域得到了广泛的关注。本文系统地研究了发光共价有机骨架(LCOFs)的合成策略,并对基于键型分类的发光共价有机骨架进行了综述。本文进一步对LCOFs在发光、圆偏振光、荧光成像、生物医学、化学和生物传感等多个领域的广泛应用进行了全面的总结和强调。最后,讨论了LCOFs在合成方法、结构设计和光学性能等方面面临的主要挑战和未来发展方向。本文综述有助于研究者快速了解该领域的研究现状,并为后续的相关研究工作指明方向。有望促进LCOFs合成技术的进一步发展和应用拓展,具有重要的学术价值。
