Aqueous-phase detection of antibiotics and nitroaromatic explosives by an alkali-resistant Zn-MOF directed by an ionic liquid

Abstract

An alkali-resistant 3D anionic Zn-MOF directed by [BMI]Br ionic liquid has been synthesized for aqueous-phase detection of antibiotics and nitroaromatic explosives.

Recent Progress in Metal-Organic Framework Based Fluorescent Sensors for Hazardous Materials Detection

“…Nitro explosives, such as 2,4,6-trinitrophenol (TNP), 2,4,6-trinitrotoluene (TNT), cyclotrimethylene trinitramine (RDX), 2,4-dinitrotoluene (2,4-DNT), and so on, are widely used in military production and industrial blasting. These compounds are not only explosive, but also toxic, hard to degrade, carcinogenic, and can cause vomiting, convulsions, neurological disorders, and even death after introduction into the human body [ 128 , 129 ]. Therefore, the development of rapid trace detection technology for nitro explosives is of great significance to prevent terrorist attacks, maintain public safety, and safeguard human health.…”

Sensing mechanism elucidation of a chemosensor based on a metal‐organic framework selective to explosive aromatic compounds

“…According to literature, deactivation of the luminescent is produced by the transfer of electrons, after a photo‐induced excitation, between the CB of MOF and the LUMO of the analyte. [ 66,67 ] Finally, the calculations of the Zn‐MOF‐toluene system showed that the active molecular orbitals are similar to the Zn‐MOF without a guest. It should also be noted that, according to experimental observations, in the presence of toluene, fluorescence attenuation is not observed.…”

An Mn(II) cluster–based coordination framework derived from a C3 symmetric ligand: Synthesis, structure, and magnetic properties

“…Based on the above considerations, each L 3− ligand acts as a 3-connected node, meanwhile each [Mn 6 ] cluster can be considered as a 10-connected node. Thus, the overall 3D network of 1 can be rationalized as a (3,10)-c net with point symbol {4 10 •5 8 •6 16 •7 2 •8 9 } {4 12 •5 6 .6 14 •7 10 •8 3 }{4 2 •5} 2 {4 3 } 4 (Figure 4).…”

“…Studies of coordination frameworks, especially of metalorganic frameworks (MOFs) or porous coordination polymers (PCPs), have focused on their structural and chemical diversities as well as their potential structure-related applications, 1 for instance, gas storage and separation, [2][3][4] catalysis, [5][6][7] magnetism, 8,9 and chemical sensing. [10][11][12] Importantly, magnetic coordination frameworks have shown great promise due to their interesting magnetism and significant potential applications in high-density information storage, quantum computing, and magnetic refrigeration. [13][14][15][16][17][18] Consequently, many strategies have been developed to control the self-assembly process of magnetic coordination frameworks.…”
