合成了一种新的苯甲酰肼Schiff碱化合物，并对其结构进行了表征。与其他常见金属离子相比，该探针对Al 3+具有较高的亲和力和灵敏度，与Al 3+络合后在443 nm处产生显著的荧光增强，并伴随着乙醇相吸收光谱的变化。在优化的实验条件下，该探针对Al 3+的动态响应范围为5.0×10 - 7 ~ 4.5×10 - 6 M，检出限为1.1×10 - 7 M。版权所有© 2015 IFSA Publishing，S. L.
A new Schiff base compound derived from benzoyl hydrazine has been synthesized and characterized as an Al 3+ -selective fluorescent probe. Compared to other common metal ions, the proposed probe shows high affinity and sensitibity towards Al 3+ , and complexing with Al 3+ triggers a prominent fluorescence enhancement at 443 nm, accompanied by the change in the absorption spectrum in ethanol phase. With the optimized experimental conditions, the probe exhibited a dynamic response range for Al 3+ from 5.0×10 -7 M to 4.5×10 -6 M with a detection limit of 1.1×10 -7 M.
