摘　　要：A microporous luminescent metal-organic framework [Zn4L2（H2O）2]＇（H2O）m（DMA）n （1） （H4L=5,5＇-（（1H-pyrazole-3,5-di- carbonyl）bis（azanediyl））diisophthalic acid, DMA=N,N-dimethylacetamide） was synthesized and characterized by infrared ra- diation （IR）, thermogravimetric analyses （TGA）, powder X-ray diffraction spectra （PXRD） and X-ray diffraction. Complex 1 has a three dimensional （3D） framework, which can be simplified as 5,5,5,5-c net with the Schlafi symbol of {43.64.83} {44.65.8 } {45.65 }2. This luminescent metal-organic framework （MOF） shows selectively sensitive to nitrobenzene and series of nitroaromatic explosives such as 4-nitrotoluene, 1,4-dinitrobenzene, 1,3-dinitrobenzene and 2,4-dinitrotoluene, and exhibits well recyclability. So complex 1 could be used to detect nitroaromatic explosives as a selective sensing material.A microporous luminescent metal-organic framework [Zn_4L_2(H_2O)_2].(H_2O)_m(DMA)_n(1)(H_4L=5,5'-((1H-pyrazole-3,5-dicarbonyl)bis(azanediyl))diisophthalic acid, DMA=N,N-dimethylacetamide) was synthesized and characterized by infrared radiation(IR), thermogravimetric analyses(TGA), powder X-ray diffraction spectra(PXRD) and X-ray diffraction.
