A sodalite-type porous metal-organic framework with polyoxometalate templates, H(3)[(Cu(4)Cl)(3)(BTC)(8)](2)[PW(12)O(40)]·(C(4)H(12)N)(6)·3H(2)O (NENU-11; BTC = 1,3,5-benzenetricarboxylate), was obtained by a hydrothermal reaction. As a reasonable candidate for eliminating nerve gas, NENU-11 displays good adsorption behavior for dimethyl methylphosphonate (15.5 molecules per formula unit). In virtue of the catalytic activity of polyoxometalate guests, this nerve gas mimic could be facilely decomposed by a hydrolysis reaction.

A new lanthanide metal-organic framework was constructed using a tripodal flexible zwitterion ligand (H3LBr3) which takes a chair-shaped configuration. The luminescence of the compound displays highly selective sensing of the Fe(3+) ion and nitrobenzene.

Because of serious environmental pollutions, the detection of hazardous and explosive nitro-aromatic compounds using metal−organic frameworks (MOFs) has been a promising research field in the current scenario. Here, we report a new fluorescent MOF, [Zn 2 (TCPE)(tta) 2 ]•2DMF•4H 2 O•2Me 2 NH 2 + (HNU-34, H 4 TCPE = 1,1,2,2-tetra(4-carboxylphenyl)ethylene, 1H-tta = 1H-tetrazole), which possesses a three-dimensional configuration and one-dimensional channels along the c-axis. It can serve as a luminescence sensor for the detection of nitrophenol explosives through different quenching effects, especially for mononitrophenol and dinitrophenol. The detection limits of 2,6-dinitrophenol and trinitrophenol are 29.45 and 36.15 nM, respectively, which are among the high level of the reported MOF sensors, especially for dinitrophenol.
