Two Co(II) and Cu(II) complexes, {[Co(Htpim)2(H2O)2](IPA−OH)}n (1) and {[Cu(Htpim)2(H2O)2](IPA−OH)}n (2) (Htpim=2,4,5‐tri(4‐pyridyl)‐imidazole, and H2IPA−OH=5‐hydroxyisophthalic acid), have been solvothermally synthesized by mixed‐ligand strategy and structurally characterized by elemental analyses, IR spectra and X‐ray diffraction (XRD) analyses. Single crystal XRD analyses indicate that 1 and 2 are almost isostructural and show 1D chain structures. Moreover, 1 can sensitively detect Mg2+ ions through turn‐on luminescence. Meanwhile, 2 can highly sensitively detect Ca2+ and SCN ions as a luminescence sensor.

具有2,4,5-三(4-吡啶基)-咪唑和5-羟基间苯二甲酸的两种钴(II)和铜(II)配合物作为Mg2 +,Ca2 +和SCN-离子的开启发光传感器

两个Co(II)和Cu(II)络合物,{[Co(Htpim)2(H 2 O)2 ](IPA-OH)} n1)和{[Cu(Htpim)2(H 2 O)2 ](IPA-OH)} n2)(Htpim = 2,4,5-三(4-吡啶基)-咪唑和H 2 IPA-OH = 5-羟基间苯二甲酸),是通过混合配体溶剂热合成的。通过元素分析,IR光谱和X射线衍射(XRD)分析来表征该策略的结构。单晶XRD分析表明12几乎是同构结构,并显示1D链结构。而且1可以通过开启发光灵敏地检测Mg 2+离子。同时,2可以高度灵敏地检测的Ca 2+和SCN -离子作为发光传感器。
