英文摘要: Abstract(#br)A dual-function probe BHMH was synthesized and characterized functioned with benzothiazole as signal unit for the simultaneous detection of Zn 2+ and Al 3+ DMF/H 2 O (1/1, v/v, 0.01 M HEPES, pH = 6.0). Probe BHMH achieved in the recognition of Zn 2+ and Al 3+ both through obvious fluorescence turn-on and absorbance ratiometric response. The limit of detection (LOD) according to the titration of fluorescence for Zn 2+ and Al 3+ were 1.27 × 10 − 7 M and 1.42 × 10 − 7 M, respectively. Furthermore, the significant color changes could be detected by naked eye whatever under ultraviolet-lamp or daylight. According to Job plot, the binding ratio of BHMH with Zn 2+ and Al 3+ were determined as 1:1 and 2:1, respectively. The binging detail was further confirmed by 1 H NMR titration...
