Abstract Metal–organic frameworks (MOFs) represent a unique class of porous materials with tremendous potential for diverse applications. A key factor contributing to their versatility is ability precisely introduce functional groups at specific positions within pores and crystals. This review explores two prominent strategies achieving the positional functionalization MOFs: post‐synthetic ligand exchange (PSE) MOF‐on‐MOF. In PSE, existing ligands solid‐state MOFs can be selectively replaced by desired in solution through dynamics. invasive provides flexible approach fine‐tuning surface target functionality. Conversely, MOF‐on‐MOF are additive methodologies involving controlled growth one MOF layer onto another. The functionality core shell (or surface) independently controlled. critically examines examples, strengths, limitations, applications these strategies, emphasizing significance advancing field paving way tailored multifunctional precise properties.

Abstract Anthropogenic carbon dioxide (CO 2 ) emissions pose a significant threat to the delicate balance between human society and natural environment. Carbon capture sequestration is technology designed selectively CO generated from power plants industrial facilities, preventing them entering atmosphere. Diamine‐modified metal–organic frameworks (MOFs) show promising capabilities in achieving remarkable capacities, highlighting their potential for effective applications. Herein, using MOF‐74 type frameworks, we discussed our various methodologies enhance adsorption capacity, while also tackling issue of maintaining structural integrity over prolonged periods, especially humid environments. The challenges prospects by diamine‐functionalized hydrophobic MOFs are highlighted.

Abstract In terms of safety and emergency response, identifying hazardous gaseous acid chemicals is crucial for ensuring effective evacuation administering proper first aid. However, current studies struggle to distinguish between different vapors remain in the early stages development. this study, we propose an on-site monitorable vapor decoder, MOF-808-EDTA-Cu, integrating robust MOF-808 with Cu-EDTA, functioning as a proton-triggered colorimetric decoder that translates anionic components corrosive acids into visible colors. The sensor exhibits cyan-to-yellow shift when exposed HCl can visually differentiate various acidic (HF, HBr, HI) through unique color changes. Furthermore, compatibility MOF-based multiple metal ions having atomic-level dispersion broadens its discrimination range, enabling identification six colorless within single domain. Additionally, by incorporating flexible polymer, MOF-808-EDTA-Cu has been successfully processed portable miniaturized sensor, exhibiting distinct changes be easily monitored naked eye camera sensors. This provides experimental validation practical capable 24-hour monitoring real world.

Abstract 2,2′‐Bipyridine (BPY) is a versatile organic ligand, well known for its strong metal‐chelating properties, which make it crucial component in coordination chemistry. When integrated into metal–organic frameworks (MOFs), BPY significantly enhances the material's particularly catalysis, due to ability coordinate with wide range of metal ions. This review focuses on metalation BPY‐incorporated MOFs (MOF‐BPYs), an emphasis secondary cations at sites. The metals are categorized first‐, second‐ and third‐row transition metals, other highlighting key examples such as Pd, Mo, Cu, Fe. synergistic interactions between centers MOF framework, contribute enhanced catalytic performance MOF‐BPYs, explored detail. also addresses mixed‐metal systems, emphasizing their unique properties applications. Furthermore, strategies metalation, including pre‐functionalization prior synthesis post‐synthetic modification, critically examined. Finally, stability parent MOFs—particularly Zr‐based frameworks, robustness—is discussed relation overall MOF‐BPY materials.

Constructing high-dimensional metal–organic framework (MOF) materials that cannot be reached by direct methods is demanding. We herein report the construction of a two-dimensional (2D) copper(I) iodide MOF via an add-and-remove strategy second metal component (HgI2). The networking reaction O2S2-macrocycle (L) with CuI bridging exocyclic coordination under condition was unsatisfactory because its one-dimensional (1D) product {[(μ4-Cu3I3)(L)2]·2CH3CN·CH2Cl2}n (1) low yield. Alternatively, self-assembly L mixture and HgI2 allows generation 2D heterobimetallic Cu(I)/Hg(II)-MOF {[Cu2(μ-Hg2I4)(L)2(CH3CN)2I2]·toluene}n (2, brick wall) cross-linked μ-Hg2I4 square dimers exocoordination mode. When crystals 2 were immersed in methanol, converted to desired Cu(I)-MOF [(μ4-Cu2I2)(L)2]n (3, grid) replacement cross-linker μ4-Cu2I2 solvent-assisted etching. Interestingly, this 2D–[1D]*–2D conversion process proceeds SCSC mode completed dimerization open coordinating site CuI* form node (2CuI* → Cu2I2), preserving dimensionality. discussed based on PXRD, EDX, AFM, TGA, NMR data.
