Abstract

A novel bis-rhodamine derivative BRU was designed and synthesized in a simple way. In aqueous media, BRU could efficiently recognize Fe3+and Al3+among other metal ions with different color appearances through a turn-on colorimetric response. In the presence of Fe3+or Al3+, BRU solution also displayed enhanced fluorescent emission. According to the detection limit, BRU had high recognition sensitivity towards Fe3+and Al3+based on either colorimetric absorbance or fluorescent emission. Interestingly, BRU bound to Fe3+or Al3+with a simple 1:1 mode in CH3OH and a 1:2 mode in CH3OH/H2O, displaying solvent-dependent binding property. In addition, the in situ generated BRU-Fe3+and BRU-Al3+complex exhibited fluorescence turn-off and color disappearance towards carbonate among other anions. These provide a potential application in sequential detection of Fe3+, Al3+and carbonate with naked-eyes.
