RESUMO
A new Rhodamine B derivative RBMAB, namely 3-amino-N-(2-(3',6'-bis (diethylamino)-3-oxospiro[isoindoline-1,9'-xanthen]-2-yl)ethyl)benzamide, was designed, synthesized and structurally characterized to develop a chemosensor. The studies show that RBMAB exhibits high selectivity toward Fe3+ among many other metal cations in an ethanol-H2O (3:2, v/v, PBS buffer, 1.2 mmol L-1, pH 7.2) solution. It has a low detection limit of 0.021µm. Fluorescence microscopy experiments further demonstrate that RBMAB can be used as a fluorescent probe to detect Fe3+ in living cells.
