摘要：

The two-dimensional (2D) metal-organic framework (MOF) [Cd(TPTZ)(H2O)(2)(HCOOH)(IPA)(2)](n) (1; TPTZ={4-[4-(1H-1,2,4-triazol-1-yl)phenyl]phenyl}-1H-1,2,4-triazole, IPA=isophthalic acid) has been constructed with the pi-electronrich aromatic ligand TPTZ, auxiliary ligand IPA, and the metal Cd2+ ion with a d(10) configuration under solvothermal conditions. Complex 1 exhibits a strong ligand-originated photoluminescence emission, which is selectively sensitive toward electron-deficient nitroaromatic compounds, such as nitro-benzene (NB), 1,3-dinitrobenzene (m-DNB), and 1,4-dinitrobenzene (p-DNB), and nitro-aliphatic compounds, such as nitromethane (NM) and tris(hydroxymethyl) nitromethane. This property makes complex 1 a potential fluorescence sensor for these chemicals. Single-crystal X-ray diffraction studies revealed that dinuclear cadmium building units were further bridged by TPTZ ligands to give a four-connected uninodal net with the Schlafli symbol of [4.6(3).4.6(3).6(2).6(4)].
