A novel coumarin derivatives based fluorescent chemosensor CBH was designed and synthesized by Schiff base reaction, which was connected by 7-(N,N-diethylamino) coumarin-3-aldehyde and 3-methyl-2-benzothiazolinone hydrazone through C=N. X-ray single crystal structure analysis indicated that two aromatic groups of the CBH were almost in the same plane. It displayed enhancement of the fluorescent intensity and absorbance when the sensor CBH interacted with Hg ions. The chemosensor CBH exhibited a good sensitive and selective recognition towards Hg ions in the presence of other important relevant metal ions.
一种新型香豆素衍生物荧光化学传感器 CBH 通过席夫碱反应设计和合成，由 7-(N,N-二乙基氨基)香豆素-3-醛和 3-甲基-2-苯并噻唑啉酮腙通过 C=N 连接。X 射线单晶结构分析表明，CBH 的两个芳基基团几乎在同一平面上。当传感器 CBH 与 Hg 离子相互作用时，其荧光强度和吸光度增强。该化学传感器 CBH 在存在其他重要相关金属离子的情况下对 Hg 离子表现出良好的灵敏选择性识别。
