| 摘 要： | 设计合成了一种基于萘酰亚胺为发光团的Zn2+荧光探针.相对于其他常见金属离子,该探针对Zn2+具有较好的选择性.探针对Zn2的识别机理为Zn2+的加入导致C=N异构化受阻,荧光增强.探针对Zn2+的线性检出范围为0.3 ～2.0μmol/L,检出限为0.15 μmol/L.

| Abstract: | In this study,an aphthalimide fluorescent probe for selectively detecting Zn2+ was designed.Compared to other metal ions,our proposed probe showed high selectivity to Zn2+.The " off-on " enhancement of fluorescent of probe was due to the rotation restriction of C=N bonds in naphthalimide caused complexed with Zn2+.The linear range of probe to Zn2+ was 0.3 ～ 2.0 μmol/L with a detection limit of 0.15 μmol/L. |
