A 3D metal-organic framework {[Cd(5-Brp)(dpa)]·0.5DMF·HO} (1) was successfully synthesized and characterized, which markedly recognized iron ions under the induction of an amino group. With the concentration of Fe increasing, the emission of 1 first declined, then enhanced with a red shift and was finally quenched, which was different from the reference compound [Cd(5-Brp)(bpp)(HO)] (2). This result drew our attention to amine induced ion-exchange. This peculiar phenomenon inspired us to construct an effective ion detector.
成功合成并表征了一种三维金属有机骨架{[Cd(5-Brp)(dpa)]·0.5DMF·H₂O} (1)，其在氨基诱导下对铁离子具有显著的识别作用。随着铁离子浓度的增加，1的发射先下降，然后增强并发生红移，最终猝灭，这与参考化合物[Cd(5-Brp)(bpp)(H₂O)] (2)不同。这一结果使我们关注到胺诱导的离子交换。这种奇特的现象激发我们构建一种有效的离子探测器。
