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).
