摘　　要：自主合成一种以Schiff-base结构单元为识别位点的萘酰亚胺类荧光探针,该化合物结构经IR、NMR、MS以及元素分析确定。详细考查其对不同金属离子的光谱分辨能力,探针对Cu2+实现"on-off"的光开关效应,表现出较好的选择性,而其他金属离子的加入没有引起明显的光谱变化。在乙醇相中,探针对Cu2+的检出限为5.3×10-7mol/L。实验结果表明:该探针可以用于Cu2+的分析检测。A new fluorescent probe derived from naphthalimide with Schiff-base unit as reorganization site was synthesized,and the structure of the new compound was characterized by IR,NMR,MS and elemental analysis. The selectivity of this probe was studied in detail, and the results exhibited that this probe had good selectivity to Cu2 ＋over a series of metal ions in ethanol. With the optimized conditions, the detection limit 5.3 ×10-7mol/L was obtained. Study showed that this newly synthesized probe could be used for detecting Cu2＋.
