A novel probe based on ferrocenyl-1,3,4-thiadiazol-containing Schiff base was synthesized by the reaction of 5-ferrocenyl-1,3,4-thiadiazol-2-amine and 4-(diethylamino)salicylaldehyde, and characterized by IR, NMR, HRMS and X-ray analysis. UV-vis spectral and fluorescence property of the probe were investigated. The probe can be used to colorimetric sensitive and selective fluorescent recognition of Cu(2+) in buffer solution. Moreover, the probe can detect Cu(2+) by electrochemical method. Additionally, the Schiff base was successfully used as a selective and sensitive fluorescent probe for monitoring Cu(2+) ions in living cells.
一种基于含二茂铁基-1,3,4-噻二唑的席夫碱的新型探针通过 5-二茂铁基-1,3,4-噻二唑-2-胺和 4-(二乙氨基)水杨醛的反应合成，并通过红外光谱、核磁共振、高分辨质谱和 X 射线分析进行了表征。研究了探针的紫外可见光谱和荧光性质。该探针可用于缓冲溶液中铜（Ⅱ）的比色敏感和选择性荧光识别。此外，该探针还可以通过电化学方法检测铜（Ⅱ）。此外，该席夫碱还成功地用作监测活细胞中铜（Ⅱ）离子的选择性和灵敏荧光探针。
