A novel luminescence MOF has been successfully prepared by the coordination assembly of CdCl2 and bis(imidazol-1-yl)methane (BIM) with the formula of [Cd(BIM)2Cl2]n. BIM and CdCl2 are coordinated with each other to form a 3D skeleton based on 1D Cd-based chain, which is characterized by many technologies, such as single crystal X-ray diffraction, thermogravimetric analyses, elemental analysis, luminescence spectrum, and UV–Vis absorption spectrum. Thanks to good water stability and preferable photoluminescence properties, this MOF shows a luminescence turn-off phenomenon towards Fe3+ cation and nitrofurantoin (NFT) antibiotic with the Ksv value of 9.59 × 103 M−1 (R2 = 0.9913) and 1.48 × 105 M−1 (R2 = 0.9903) for Fe3+ and NFT. Additionally, the as-made sample possesses high selectivity and good reusability.

基于Cd(II)的MOF作为双响应发光探针,用于高选择性检测Fe 3+阳离子和呋喃妥因

通过CdCl 2(咪唑-1-基)甲烷(BIM)配位[Cd(BIM)2 Cl 2 ] n配位,成功制备了新型发光MOF 。BIM和CdCl 2相互配合形成基于1D Cd基链的3D骨架,该骨架具有许多技术的特征,例如单晶X射线衍射,热重分析,元素分析,发光光谱和UV–可见吸收光谱。由于良好的水稳定性和较好的光致发光特性,该MOF表现出了对K 3+的Fe 3+阳离子和硝基呋喃妥因(NFT)抗生素的发光关闭现象。 Fe 3+和NFT的sv值为9.59×10 3 M -1(R 2  = 0.9913)和1.48×10 5 M -1(R 2 = 0.9903)。另外,制成的样品具有高选择性和良好的可重复使用性。
