A new highly selectivefluorescent probe based on 2-(2′-aminolphenyl)-4-hydroxymethylthiazole (1) was developed for the detection of copper and iodide ions in ethanol. Probe 1 selectively detected Cu2+ through a “switch off” response, showing a good association constant (Ka = 1.43 × 105 M−1) and binding with Cu2+ ions in a 1:1 stoichiometry. An in situ generated 1-Cu2+ (1:1) ensemble detected I− ions
开发了一种基于2-(2'-氨基苯基)-4-羟甲基噻唑(1)的新型高选择性荧光探针,用于检测乙醇中的铜和碘离子。探针1通过“关闭”响应选择性地检测到Cu 2+,显示出良好的缔合常数(K a = 1.43×10 5 M -1)并以1:1的化学计量比与Cu 2+离子结合。一个原位生成的1-Cu系2+(1:1)检测到的合奏我-离子依次通过一个“接通”的响应。“关闭由于分子内电荷转移(ICT),Cu 2+离子选择性配位发生了反应。的集合1个铜(II)显示出朝向碘化物较高的选择性比对任何其它阴离子减少所致的Cu 2+成Cu +由I -和随后的络合1。
