Luminescent Microporous Metal-Organic Framework for the Fast and Reversible Detection of High Explosives

Sensors and sensitivity: A highly luminescent microporous metal-organic framework, [Zn₂(bpdc)₂(bpee)] (bpdc=4,4'-biphenyldicarboxylate; bpee=1,2-bipyridylethene), is capable of very fast and reversible detection of the vapors of the nitroaromatic explosive 2,4-dinitrotoluene and the plastic exp...

Summary:Sensors and sensitivity: A highly luminescent microporous metal-organic framework, [Zn₂(bpdc)₂(bpee)] (bpdc=4,4'-biphenyldicarboxylate; bpee=1,2-bipyridylethene), is capable of very fast and reversible detection of the vapors of the nitroaromatic explosive 2,4-dinitrotoluene and the plastic explosive taggant 2,3-dimethyl-2,3-dinitrobutane, through redox fluorescence quenching with unprecedented sensitivity (see spectra).
