Abstract A new 3D coordination polymer [NH2(CH3)2]2[Zn7L4(DMF)2(H2O)3]·19H2O (1) (L = 2,3′,5,5′-biphenyl tetracarboxylic acid) has been solvothermally synthesized and structurally characterized by IR, elemental analysis and single-crystal X-ray diffraction. Single-crystal X-ray diffraction studies indicate that 1 exhibits 3Dframework with a one-dimensional (1D) channel. The luminescence properties have been
摘要 一种新的 3D 配位聚合物 [NH2(CH3)2]2[Zn7L4(DMF)2(H2O)3]·19H2O (1) (L = 2,3',5,5'-联苯四甲酸)通过红外、元素分析和单晶 X 射线衍射合成和结构表征。单晶 X 射线衍射研究表明 1 展示了具有一维 (1D) 通道的 3D 框架。已经研究了发光特性,结果表明1在室温下在固态和甲醇悬浮液中都显示出强烈的荧光发射。更有趣的是,Fe3+的加入导致1的荧光强度减弱,这意味着它可以作为Fe3+的发光探针。
