A new luminescent terbium-metal-organic framework [Tb3(L)2(HCOO)(H2O)5]·DMF·4H2O (1) (H4L = 4,4'-(pyridine-3,5-diyl)diisophthalic acid) has been successfully assembled by Tb(3+) ions and an undeveloped pyridyl-tetracarboxylate. Compound 1 exhibits a 3D porous (3,8)-connected (4.5(2))2(4(2).5(12).6(6).7(5).8(3)) topological framework with fascinating 1D open hydrophilic channels decorated by uncoordinated Lewis basic pyridyl nitrogen atoms. In particular, the Tb-MOF (1) can detect Cu(2+) ions with high selectivity and sensitivity, and its luminescence is nearly entirely quenched in N,N-dimethylformamide (DMF) solution and biological system. In addition, 1 still has high detection for the trace content of nitromethane with 70 ppm, which suggests that 1 is a promising example of dual functional materials with sensing copper ions and nitromethane.
一种新型发光铽基金属有机框架化合物[Tb3(L)2(HCOO)(H2O)5]·DMF·4H2O (1)（H4L = 4,4'-(吡啶-3,5-二基)二间苯二甲酸）已通过Tb(3+)离子和一种未开发的吡啶基四羧酸成功组装而成。化合物1呈现出一种三维多孔的(3,8)-连接(4.5(2))2(4(2).5(12).6(6).7(5).8(3))拓扑框架，具有由未配位的路易斯碱性吡啶氮原子修饰的迷人的一维开放亲水通道。特别地，铽基金属有机框架(1)能够高选择性和高灵敏度地检测Cu(2+)离子，并且其发光在N,N-二甲基甲酰胺(DMF)溶液和生物体系中几乎完全猝灭。此外，1对痕量的70 ppm硝基甲烷仍具有高检测能力，这表明1是一种有前景的兼具检测铜离子和硝基甲烷功能的双功能材料实例。
