2-(1'-Acetyl-ferrocenyl) benzothiazole (FcSO) probe was synthesized by the acetylization reaction of 2-ferrocenyl benzothiazole, which was obtained from the cyclization reaction of ferrocenecarboxaldehyde with 2-aminothiophenol. Crystal and molecule structures of FcSO probe were characterized by spectra methods and X-ray single crystal diffraction analysis. The recognition ability to Al3+, Cr3+, Fe3+ ions of FcSO probe was researched by three analytical methods of UV-Vis, fluorescence and electrochemistry. The results show that the recognition to Al3+, Cr3+, Fe3+ ions of FcSO probe is effective via three channels, and the detection limits of FcSO probe to Al3+, Cr3+, Fe3+ ions are 7.456×10-6, 3.72×10-6 and 1.35×10-5 mol/L, respectively. 1H NMR research results indicate that the acetyl, ferrocenyl and benzothiazole groups of FcSO probe play important roles in recognizing Al3+, Cr3+, Fe3+ ions.

Key words: crystal structure, acetyl-ferrocenyl-benzothiazole probe, multi recognition method, trivalent metal ion
