• Abstract: The thiophene-modified rhodamine 6G (GYJ) has been synthesized as a novel chemosensor. The sensor has sufficiently high selectivity and sensitivity for the detection of Fe3 and Al3 ions (M3 ) by fluorescence and ultraviolet spectroscopy with a strong ability for anti-interference performance. The binding ratio of M3 -GYJ complex was determined to be 2:1 according to the Job's plot. The binding constants for Fe3 and Al3 were calculated to be 3.91 x 10(8) and 5.26 x 10(8) M-2, respectively. All these unique features made it particularly favorable for cellular imaging applications. The obvious fluorescence microscopy experiments demonstrated that the probes could contribute to the detection of Fe3 and Al3 in related cells and biological organs with satisfying resolution.
