Rational synthesis of an exceptionally stable Zn(II) metal–organic framework for the highly selective and sensitive detection of picric acid

Based on an organic ligand involving both carboxylate and tetrazole groups, a chemically stable Zn(II) metal–organic framework has been rationally synthesized and behaves as a fluorescence chemosensor for the highly selective and sensitive detection of picric acid, an extremely hazardous and strong explosive.
