Low‐dimensional metal–organic frameworks (LD MOFs) have attracted increasing attention in recent years, which successfully combine the unique properties of MOFs, e.g., large surface area, tailorable structure, and uniform cavity, with the distinctive physical and chemical properties of LD nanomaterials, e.g., high aspect ratio, abundant accessible active sites, and flexibility. Significant progress has been made in the morphological and structural regulation of LD MOFs in recent years. It is still of great significance to further explore the synthetic principles and dimensional‐dependent properties of LD MOFs. In this review, recent progress in the synthesis of LD MOF‐based materials and their applications are summarized, with an emphasis on the distinctive advantages of LD MOFs over their bulk counterparties. First, the unique physical and chemical properties of LD MOF‐based materials are briefly introduced. Synthetic strategies of various LD MOFs, including 1D MOFs, 2D MOFs, and LD MOF‐based composites, as well as their derivatives, are then summarized. Furthermore, the potential applications of LD MOF‐based materials in catalysis, energy storage, gas adsorption and separation, and sensing are introduced. Finally, challenges and opportunities of this fascinating research field are proposed.

“…They combine two disciplines, namely organic and inorganic chemistry and possess many favorable characteristics, for example high surface area, high porosity, tenability, reproducibility, high sorption capacities, facile syntheses, and good possibilities for scale up . Therefore, such materials can be used in numerous applications, for instance catalysis, gas storage, gas separation, drug delivery, luminescence, solar cells, and batteries . This class of porous polymeric material is assembled by the connection of a metal ion linked together by organic bridging ligands to form 1D, 2D, or 3D structures as illustrated in Figure .…”

Evaluation of the BET Theory for the Characterization of Meso and Microporous MOFs

Surface area determination with the Brunauer–Emmett–Teller (BET) method is a widely used characterization technique for metal–organic frameworks (MOFs). Since these materials are highly porous, the use of the BET theory can be problematic. Several researchers have evaluated the BET method to gain insights into the usefulness of the obtained results and interestingly, their findings are not always consistent. In this review, the suitability of the BET method is discussed for MOFs that have a diverse range of pore widths below the diameters of N2 or Ar and above 20 Å. In addition, the surface area of MOFs that are obtained by implementing different approaches, such as grand canonical Monte Carlo simulations, calculations from the crystal structures or based on experimental N2, Ar, or CO2 adsorption isotherms, are compared and evaluated. Inconsistencies in the state‐of‐the‐art are also noted. Based on the current literature, an overview is provided of how the BET method can give useful estimations of the surface areas for the majority of MOFs, but there are some crucial and specific exceptions which are highlighted in this review.

“…Metal-organic frameworks (MOFs), are crystalline porous architectures that are composed of metal ions or clusters and organic ligand, have been emerging as very promising materials which can be applied in various fields due to their unique properties, such as high surface areas, controllable pore size. MOFs have been proposed to be promising in many applications, such as gas storage and separation [ 6 , 7 , 8 , 9 , 10 , 11 ], catalysis [ 12 , 13 , 14 , 15 ], energy storage [ 16 , 17 ], and biomedical applications [ 18 , 19 , 20 , 21 , 22 , 23 ]. Among luminescent MOFs, Ln-MOFs have huge advantages in sensing due to their fascinating luminescence characteristics, such as high luminescence quantum yield, long luminescent life time, high color purity, and big stoke shifts.…”

Sesamol, is well-known antioxidant and can reduce the rate of oxidation and prolong expiration date. It is also potentially antimutagenic and antihepatotoxic, the detection of sesamol is important and remains a huge challenge. Herein, a new 3D alkaline earth Sr metal organic framework [Sr(BDC)·DMAC·H2O]n (BDC = benzene-1,4-dicarboxylate; DMAC = N,N-dimethylacetamide) is synthesized and a probe based on Tb3+ functionalized Sr-MOF. The Tb(3+)@Sr-MOF showed good luminescence and thermal property. Due to the energy competition between sesamol and ligand, the luminescence intensity of sesamol increases meantime luminescence intensity of Tb3+ decreases, the ratio of the emission intensities (I344/I545) linearly increases with sesamol in concentrations ranging from 1 × 10−7 to 8 × 10−4 M. Furthermore, the fluorescence-detected circular test shows that the composite Tb(3+)@Sr-MOF can serve as ratiometric sensor for sensing of sesamol. This is the first example for self-calibrated detecting sesamol based on metal-organic framework (MOF).
