Rapid and sensitive fluorescence sensing detection of nitroaromatic compounds in water samples based on pyrene functionalized nanofibers mat prepared via green approach

Three-dimensional cage zinc triazine framework compound: Fluorescence sensing of aromatic compounds containing NO2/OH groups

“…The method of rapid and quantitative detection of nitroaromatic compounds has attracted great attention. [30][31][32][33][34][35][36][37][38] The fluorescence ''turn off'' or ''turn on'' response mechanism of the MOF sensing process usually includes p-p interaction between MOFs and analyte, bonding reaction, and light-induced electron or energy transfer. 39,40 The pore size and main skeleton structure of MOFs have a huge impact on the luminescence performance.…”

Pyrenyl‐Based Aggregation‐Induced Emission Luminogen for Highly Sensitive and Selective Detection of 2,4,6‐Trinitrotoluene in Water

“…For comparison, relevant research data for TNT detection in solution were summarized in Table 1, this calculated K sv value for TNT was comparable to those reported in the literature. [9,[14][15][16][17][18] The LOD value was obtained by monitoring the fluorescence quenching after gradually adding low concentration TNT analyte (0-3 μM). The change in fluorescence intensity was plotted against analyte concentration (Figure S6) and the LOD was calculated using the equation…”

“…Compared with documented sensors in the literature, CPPyV had comparable fluorescence quenching coefficient and lower detection limit for TNT. [9,[14][15][16][17][18] However, most sensors documented in the literature can only used in organic or mixed aqueous media, while CPPyV was purposely designed for detection of TNT in aqueous media, which was more suitable for far-ranging applications.…”

An eight‐membered cyclosiloxane conjugated microporous polymer performed a rapid and sensitive fluorescence detection of 2,4‐dinitrophenol

“…As important essential chemical raw materials, NACs are mainly used in the production of pesticides, medicines, explosives, dyes and other chemical products 26 . However, as their widespread application cause severe pollution, dissolution in water will become a high concentration of non‐biodegradable toxic organic wastewater 27 . 2,4‐dinitrophenol (DNP) is a yellow solid insoluble in ordinary solvents such as cold water, ethanol, acetic ether benzene, and chloroform which is mainly used for organic synthesis, dyes, and explosives.…”

“…26 However, as their widespread application cause severe pollution, dissolution in water will become a high concentration of nonbiodegradable toxic organic wastewater. 27 2,4-dinitrophenol (DNP) is a yellow solid insoluble in ordinary solvents such as cold water, ethanol, acetic ether benzene, and chloroform which is mainly used for organic synthesis, dyes, and explosives. The incursive pathway of DNP is mainly through inhalation, feeding, or absorption through the skin, which is directly acting on the energy metabolism process that can enable the cellular oxidation process to enhance the phosphorylation process inhibition.…”
