摘　　要：设计合成了一种用于检测Hg2+的1,8-萘酰亚胺类荧光探针(NM1),采用现代波谱技术对探针的结构进行了表征,并考察了其光谱性能。研究结果表明,NM1对Hg2+有优秀的选择性和灵敏度,它们之间的结合比为1∶1,常见共存金属离子对其测定无干扰。此外,NM1还能够可视化检测Hg2+,这对检测水质和生物体内的Hg2+具有潜在的应用价值。A 1,8-naphthalimide-based fluorescent probe(NM1)for Hg2+ion detection was designed and synthesized.It was characterized by modern spectroscopy methods.Besides,its spectral property was investigated.The results show that NM1 exhibits excellent sensitivity and selectivity to Hg2+.The combination proportion is 1∶1.Common coexistent metal ions have no interference in detection.Furthermore,NM1 can achieve visual detection of Hg2+.Those results showed that NM1 has potential application value for the detection of Hg2+in water and in living systems.
