摘　　要：合成了1,1,2-三甲基-1H-苯并[e]吲哚克酮酸菁(TBIC),利用傅里叶红外光谱仪、核磁共振仪对其结构进行表征。通过紫外-可见分光光度计、荧光-分光光度计对此化合物的性能进行研究,发现加入Fe^(3+)后,溶液由紫色变为无色,紫外和荧光光谱均发生明显变化,表现出较短的响应时间、较低的检测限和对其他金属离子较好的抗干扰性能。结果表明,在多种金属离子存在的水溶液中,该化合物能够高选择性和高灵敏度地识别Fe^(3+),可用作检测微量Fe^(3+)的比色和荧光探针。1,1,2-Trimethyl-1 H-benzo[e]indole-croconaine was synthesized,and its structure was characterized by fourier infrared spectroscopy and nuclear magnetic resonance.The performance of the compound was studied by ultraviolet-visible spectrophotometer and fluorescence-spectrophotometer.It was found that after adding Fe^(3+),the solution changed from purple to colorless,and both the ultraviolet and fluorescence spectra were changed obviously,showing shorter response time,low detection limit and good anti-interference performance against other metal ions.The results shown that the compound can identify Fe^(3+) with high selectivity and sensitivity in aqueous solutions with multiple metal ions,and can be used as a colorimetry and fluorescent probe for detecting trace Fe^(3+).
