New in situ solvothermally synthesized metal-organic framework MOF-199 coating for solid-phase microextraction of volatile organic compounds from air samples

Lanthanide-based metal–organic framework materials as bifunctional fluorescence sensors toward acetylacetone and aspartic acid

“…[1][2][3][4][5][6][7][8] MOF-based fluorescence sensors for the detection of living materials or volatile organic compounds have attracted increasing attention due to their high selectivity, sensitivity and simplicity. [9][10][11][12][13][14][15] Lanthanide ions exhibit strong coordination ability, rich coordination configurations and unique f-electron structures, causing the possibilities of unique magnetism, luminescence and catalytic activity. 16,17 Therefore, the reaction of lanthanide ions with suitable ligands has become an effective way to construct multifunctional lanthanide-based MOFs (Ln-MOFs).…”

“…18,19 In particular, the photoluminescence characteristics of Ln-MOFs expand the application in molecular switches and chemical sensors. [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24] Many Ln-MOFs have been applied to detect metal cations, inorganic anions and small organic molecules. 25,26 However, there are few reports of Ln-MOFs for the detection of amino acids.…”

Latest Improvements and Expanding Applications of Solid-Phase Microextraction

“…The porous MOFs and COFs have also been fabricated as SPME fibers through the strategy of in situ growth. As shown in Figure , the stainless steel wire is etched by hydrofluoric (HF) acid before the growth of MOF-199 . For the growth of COFs, the 3-aminopropyltriethoxysilane (APTES) is used to modify the substrates with abundant −NH 2 groups, which can further react with other monomers containing −CHO groups.…”

Synthesis of metal-organic frameworks as catalyst for the conversion of carbon dioxide to cyclic carbonates

“…These adsorbents require significantly higher temperature for regeneration because the presence of water significantly decreases their adsorption capacity. The decrease in adsorption capacity, leads to a decrease in strength and heterogeneity of the electric field and thus favoring the formation of bicarbonates In the past few years, various synthetic strategies for MOF catalysts have been reported, such as ultrasonic synthesis [64] [65] [66], microwave-assisted synthesis [67], mechanochemical synthesis [68] and conventional hydrothermal/solvothermal synthesis [69]. Conventional methods normally involve the use of high temperature and pressure to achieve the formation of MOF catalyst in a shorter period [70].…”
