| Abstract: | A novel water-soluble probe(L)is designed and synthesized based on rhodamine B.The results indicate that probe L is a“turn-on”fluorescent probe with high selectivity for free M3+(Cr3+,Al3+,Fe3+)detection in pure water system(TRIS,pH=7.4).The detection limits of probe L to Cr3+,Al3+,and Fe3+are 1.57×10-5,1.43×10-5,and 6.55×10-5mol/L,respectively.The probe L has potential applications in detection of trivalent metal ions in biological systems and environments. |
