A novel polydiacetylene‐linked ligand derived from the reaction between chelidamic acid and bis(pyridin‐2‐ylmethyl)amine (PDA‐CB) showed excellent selectivity and sensitivity for Cd2+ ions compared with other metal ions, including Zn2+. An obvious color change between PDA‐CB and PDA‐CB + Cd2+ is clearly visible to the naked eye. The Cd2+‐responsive color change of PDA‐CB is attributed to the coordination between Cd2+ and CB ligand units and has been characterized by 1H NMR titration.

聚二乙炔用螯合物和2,2'-Dipicolylamine功能化,对镉离子的比色响应

一种新的聚二乙炔连接的配体,其与氯胺酸和双(吡啶-2-基甲基)胺(PDA-CB)反应生成,与其他金属离子(包括Zn 2+)相比,对Cd 2+离子具有极好的选择性和灵敏度。肉眼可以清楚地看到PDA-CB和PDA-CB + Cd 2+之间的明显颜色变化。PDA-CB的Cd 2+反应性颜色变化归因于Cd 2+和CB配体单元之间的配位,并已通过1 H NMR滴定进行了表征。
