Isatin-Triazole-Functionalized Rhodamine: A Dual Sensor for Cu2+ and Fe3+ Ions and Its Application to Cell Imaging

摘要

A new isatin-triazole tethered rhodamine based fluorescent probe R1 (1-(2''-(4'-(((3''',6'''-bis(diethylamino)-3''-oxospiro[isoin- doline-1'',9'''-xanthen]-2''-yl)amino)methyl)-1H-1',2',3'-triazolyl) ethyl)indoline-2,3-dione) has been synthesized using click chemistry approach. Probe R1 exhibits a dual sensor property for Cu2+ and Fe3+ ions through turn-on fluorescence response. A prominent colour change from colourless to pink allows the naked eye identification of aforementioned metal ions.
