摘　　要：以一个镉配位聚合物{[Cd(L1)(1,3-bdc)(H 2O)2][Cd(1,3-bdc)(H 2O)3]·2H 2O}(1)(L1=4-(4-甲基苯基)-4H-1,2,4-三唑,1,3-bdc=间苯二甲酸根)为荧光探针,对14种金属离子识别。结果表明配合物1能够选择性识别Fe^3+,除Cu^2+外几乎不受他金属离子(Ag^+、Zn^2+、Pb^2+、Ni^2+、K^+、Hg^2+、Mg^2+、Co^2+、Cd^2+、Ca^2+、Ba^2+和Al^3+)干扰。探针配合物1的荧光强度与Fe^3+的浓度(1.0×10^-5~10.0×10^-5 mol/L)呈良好的线性关系,R^2=0.9938。A cadmium coordination polymer{[Cd(L1)(1,3-bdc)(H2O)2][Cd(1,3-bdc)(H2O)3]2H2O}(1)(L1=4-(4-methylphenyl)-4H-1,2,4-triazole,1,3-bdc=1,3-benzenedicarboxylate)was used as a fluorescent probe to identify 14 metal ions.The results showed that the compound 1 exhibited the selective to Fe^3+,and other metal ions(Ag^+、Zn^2+、Pb^2+、Ni^2+、K+、Hg^2+、Mg^2+、Co^2+、Cd^2+、Ca^2+、Ba^2+和Al^3+)did not interfere with its recognition except Cu^2+.The linear relationship was observed between the fluorescence intensity of probe compound 1 and the concentration of Fe 3+in the range of 1.0×10^-5~10.0×10^-5 mol/L.R^2=0.9938.
