摘要
在溶剂热条件下,用三羧酸衍生物5-((4-羧基苄基)氨基)间苯二甲酸(H_(3)L)和4,4’-二甲基-2,2’-联吡啶(dbpy)作为混合配体与Cd(Ⅱ)构建出具有荧光性质的配位聚合物,即[Cd_(2)(L)(dbpy)_(2)(HCOO)(H_(2)O)]·2H_(2)O(CP 1)。通过X射线单晶衍射、X射线粉末衍射和热重分析对其进行表征,结果表明CP 1是一个双核二维层状结构。此外,CP 1具有良好的荧光性,能够对水溶液中的六价铬含氧酸根离子(Cr_(2)O_(7)^(2-)和CrO_(4)^(2-))实现选择的荧光猝灭检测。
Under solvothermal conditions,a coordination polymer with fluorescence properties was constructed by using tricarboxylic acid derivative 5-((4-carboxybenzyl)amino)isophthalic acid(H_(3)L)and 4,4'-dimethyl-2,2'-bipyridine(dbpy)as mixed ligands with Cd(Ⅱ),namely[Cd_(2)(L)(dbpy)_(2)(HCOO)(H_(2)O)]·2H_(2)O(CP 1).Characterizing by X-ray single crystal diffraction,X-ray powder diffraction and thermogravimetric analysis,CP 1 was identified as a binuclear two-dimensional layered structure.In addition,CP 1 has good fluorescence,and can realize selective fluorescence quenching detection for hexavalent chromium oxylate ions(Cr_(2)O_(7)^(2-)and CrO_(4)^(2-))in aqueous solution.
