摘　　要：设计合成了一类新型的具有缺电子结构的偶氮类化学传感器(L1~L3).该类化合物对F^(-)具有明显的颜色变化响应,可用于F^(-)的可视化检测.化合物L3含有富电子基团二茂铁,通过颜色和电化学检测发现,L3只对F^(-)表现出高度选择性识别.这种由于化学结构的改变而引起的阴离子传感性质变化为开发新型的功能传感器提供了一种新的研究思路.A new class of azo-based chemosensors(L1~L3)with electron-withdrawing structure were designed and synthesized.All of them showed obvious color change toward fluoride anion,which allowed for the"naked-eye"detection.Incorporated with ferrocene unit as an electron releasing group,L3 showed selective binding ability toward fluoride anion among test anions,presenting color and electrochemical change.Such obvious variations in anion sensors resulting from change of chemical structure of hosts would provide new strategy for functional sensors.
