Synthesis of copper-based metal-organic framework for sensing nitroaromatic compounds

Synthesis, crystal structures and physicochemical performance of the triethylamine salt and copper (II) complex based on 3, 5-dinitropyrazole

“…Among them, ionic salts and coordination compounds (including metal-organic frameworks) are the hotspot materials in the investigations of EMs and they behave significant and special physicochemical performance than other neutral compounds in most cases. [1,2] Azole-based energetic ionic materials are always a fascinating calls of multi-nitrogen frameworks, which contain multiple N-N, C-N chemical bonds and stable electrovalent bond depositing sufficient energy. Since 2010, many energetic ionic compounds grounding on pyrazole were massively prepared, which were mainly consist of 3,4,5-trinitropyrazole (3,4,5-TNP)-, [3,4] 3,4,5-trinitropyrazole-1-ol (TNPO)-, [5] 4-amino-3,5-dinitropyrazole (ADNP)-, 4-nitramino-3, 5-dinitropyrazole (4-NADNP)-and 1-nitramino-3,5-dinitropyrazole (1-NADNP)-based organic salts.…”

Facile preparation of mesoporous silica coated nitrogen doped carbon dots for sensitive detection of picric acid

“…20 Many sensors-based fluorescence quenching has been reported in recent years, including fluorescent nanofibers, 21 nanofilms, 22 fluorescent-labeled polymers 23 and metal–organic frameworks. 24,25 However, the high cost of materials and complex preparation methods seriously limit their further applications. The fluorescence analysis method established by quantum dots as fluorescent materials were widely used because of the good detection effectivity for explosives.…”

Imidazole-Based Metal–Organic Framework for the “On1–Off–On2” Fluorescence-Based Detection of Picric Acid and the Adsorption of Congo Red

“…Nitroaromatic compounds (NACs), metal ions, and dyes are frequently used in the processing of raw materials and synthesis of fine chemicals, pharmaceuticals, dyestuffs, spices, explosives, and pesticides; as a result, they are frequently released as waste, making them targets for sensing and adsorption. − For example, p -nitrophenol is used to prepare the over-the-counter drugs paracetamol and phenacetin. The aromatic rings, such as phenyl rings, in NACs have characteristic electronic effects that can result in changes in the properties of MOFs upon interaction. , For example, aromatic compounds having electron-withdrawing nitro groups can result in the formation of an electron-deficient environment in the MOFs.…”
