摘　　要：使用H_(2)L配体(H_(2)L=2-(1,3-dioxo-1H-benzo[de]isoquinolin-2(3H)-yl)terephthalic acid)和Zn_(2)+通过水热反应,合成了一例基于双核{Zn_(2)(COO)_(4)}次级构筑单元的二维发光配位聚合物[Zn_(2)(L)_(2)(DMSO)_(2)(DMF)](1)(DMSO=二甲亚砜,DMF=N,N-二甲基甲酰胺)。拓扑分析表明1结构中的双核{Zn_(2)(COO)_(4)}单元可视为4连接节点,并与作为连接子的L_(2)-形成(4,4)-网拓扑构型。1表现出对Fe^(3+)离子的选择性发光猝灭响应,检测限为2.8μmol·L^(-1)。1对Fe^(3+)的检测具有良好的抗干扰性,且可通过DMF溶剂洗涤实现再生,可多次循环使用。A two-dimensional luminescent coordination polymer based on dinuclear{Zn_(2)(COO)_(4)}second buildings units,[Zn_(2)(L)_(2)(DMSO)_(2)(DMF)](1,H_(2)L=2-(1,3-dioxo-1H-benzo[de]isoquinolin-2(3H)-yl)terephthalic acid,DMSO=dimethyl sulfoxide,DMF=dimethylformamide),was synthesized by hydrothermal reaction using H_(2)L ligand and Zn_(2)+.Topological analysis shows that the dinuclear{Zn_(2)(COO)_(4)}unit can be regarded as a 4-linked node and forms a(4,4)-net topology with L_(2)-linker.1 also exhibited a selective luminescence quenching type response to Fe^(3+)with detection limit as low as 2.8μmol·L^(-1).1 has good anti-interference ability for the detection of Fe^(3+),and can be regenerated and recycled for several times by washing with DMF solvent.CCDC:2079394.
