摘要
在溶剂热条件下,利用CdI_(2)分别与邻菲啰啉(phen)、2,2′-联吡啶(bpy)反应得两个新的Cd配合物Cd(phen)_(2)I_(2)和Cd(bpy)_(2)I_(2)。通过X-射线单晶衍射、红外光谱、热重分析等方法对其表征。晶体结构分析表明,Cd(Ⅱ)离子与两个phen或bpy配体上4个N原子以及2个I原子配位形成畸变的八面体配位,借助π-π堆积和C-H…I氢键相互作用形成超分子构筑。此外,还研究了配合物Cd(phen)_(2)I_(2)对不同金属阳离子的荧光传感性能,结果表明Fe^(3+)具有较高选择性和明显的荧光猝灭响应。
Two new Cd complexes:Cd(phen)_(2)I_(2)and Cd(bpy)_(2)I_(2)were prepared under solvothermal conditions by reacting CdI_(2)with 1,10-phenoline(phen)and 2,2′-bipyridine(bpy),respectively.The complexes were characterized by using IR,TG,and X-ray single crystal diffraction.The crystal structure analysis revealed that each Cd(Ⅱ)ion is coordinated with four N atoms from the two phen or bpy ligands,and two I atoms forming a distorted octahedral coordination geometry.The supramolecule was constructed viaπ-πstacking and C-H…I hydrogen bond interactions.The fluorescent sensing of Cd(phen)_(2)I_(2)to a series of metal cations was investigated.The results showed that Fe^(3+)ion had higher selectivity and apparent fluorescence quenching response.
