A luminescent Zn-MOF for the detection of explosives and development of fingerprints

Abstract

A luminescent 3D metal-organic framework [Zn(NDA)(AMP)] = PUC1 (where, NDA= naphthalene-2,6-dicarboxylic acid and AMP = 4-aminomethyl pyridine) was synthesized under solvothermal conditions. The synthesized 3D framework was fully characterized with...

Highly selective detection of 2,4-dinitrophenol by fluorescent NH2-MIL-125(Ti) via dual-parameter sensing technology

“…1,2 Therefore, the high-reliability detection of 2,4-DNP in water environments holds great signicance in safeguarding both the environment and human health. 3,4 At present, the primary detection technologies for 2,4-DNP are Raman Spectroscopy (RS), 5 Ion Mobility Spectrometry (IMS), 6 High Performance Liquid Chromatography (HPLC), Liquid Chromatography-Mass Spectrometry (LC-MS), 7 etc. However, the advancement of these technologies in the eld is impeded by their exorbitant cost and the complexity of the necessary equipment, despite their capacity to attain a remarkable level of accuracy in pollutant detection.…”
