“…In recent years, as a new strategy to control and regulate the functions and properties of MOF materials, post‐modification has become a very useful method for modifying the active sites of organic ligands or metal nodes while maintaining the main structure of MOFs . At present, post‐synthesis modifications are mainly concentrated in three aspects: post‐ synthetic metal exchange (PSME), post‐synthetic ligand exchange (PSLE) and post‐synthetic elimination and insertion (PSE&I) …”

As a new type of highly ordered porous crystalline material, metal-organic frameworks (MOFs) have been extensively studied in many fields due to their high specific surface area and porosity, flexible modifiability and tailorability. After nearly 20 years of development, the synthesis of MOF materials has gradually evolved from exploration and trial to precise design. The synthesis method has also evolved from an early one-step synthesis to the coexistence of various synthesis strategies, including functional-oriented microstructural design optimization, pore size adjustment, and secondary structural unit modification, enabling MOF materials to expand their potential applications in many fields. In this review, we mainly discuss the pore regulation of function-oriented MOF through different synthesis strategies, including (1) direct synthesis, (2) post-synthesis modification (PSM), (3) building block replacement (BBR), (4) pore space partition (PSP), (5) construction of multi-mesoporous MOF, (6) dynamic septal ligand insertion, and discuss the relationship between related performance optimization through framework structure and pore environment/size optimization.Xiurong Zhang (top left) was born

“…18 Coupling agents, metal joints, pore characteristics, and surface environment can be used to adjust the structure of a MOF to upgrade its structural stability and performance. 85 The drawbacks to post-synthetic modication are that it can be timeconsuming (1-5 days), and the production rate depends on the pore diameter under standard conditions. Liquid phase PSM (LP-PSM) and vapor phase PSM (VP-PSM) are the two pathways that are commonly practiced for post-synthetic modication.…”

“…In this regard, silica-based nanocomposites, different carbon-based nanosorbents, metal-organic frameworks (MOFs), and covalent organic frameworks (COFs) have been recently employed for sampling and separation of organic and inorganic analytes in different matrices [16]. MOFs or metal-organic coordination polymers (MOCPs) are microspore advanced polymeric crystalline materials that are made from hybrid inorganic-organic molecules [17]. MOFs have some unique properties, such as permanent nanoscale porosity, high surface area, costly diversity in their structures, tunable pore size, structure flexibility, and high loading capacity [18].…”

The performance of headspace solid-phase microextraction (HS-SPME) was upgraded by easy and low-cost preparation of a new nanocomposite fiber. A polypyrrole/chromium-based metal–organic framework, PPy@MIL-101(Cr), nanocomposite was electrochemically synthesized and simultaneously coated on a steel wire as a microextraction sorbent. The morphology and chemical structure of the prepared nanocomposite was characterized by Fourier-transform infrared spectrometry (FT-IR), scanning electron microscopy (SEM), and energy dispersive X-ray analysis (EDX) techniques. The microsorbent was used for sampling of methyl-tert-butyl ether (MTBE) in solid samples, through an HS-SPME sampling strategy, followed by GC-FID measurement. The optimal experimental conditions, including extraction temperature, extraction time, and GC desorption conditions, were evaluated and optimized. The proposed procedure showed good sensitivity (limit of detection was 0.01 ng·g−1) and precision (relative standard deviation was 8.4% for six replicated analyses). The calibration curve was linear over the range of 5–40,000 ng·g−1, with a correlation coefficient of 0.994. The limit of quantification was 0.4 ng·g−1. The fabricated fiber exhibited good repeatability and reproducibility for the sampling of MTBE, with average recovery values of 88–114%. The intra-fiber and inter-fiber precisions were found to be 8.4% and 19%, respectively. The results demonstrated the superiority of the PPy@MIL-101(Cr)-coated fiber in comparison with handmade (polypyrrole, PPY) and commercial fibers (polyacrylate, PA; polydimethylsiloxane, PDMS; and divinylbenzene/carboxen/polydimethylsiloxane, DVB/CAR/PDMS) for the analysis of solid samples. The developed method was successfully employed for the analysis of MTBE in different soil samples contaminated by oil products.
