摘　　要：设计和合成了一种苝二酰亚胺-冠醚衍生物。分别溶于DMF、DMSO和乙腈,测定其紫外可见吸收光谱,然后再添加微量碘化锂固体,继而分别测定紫外可见吸收光谱。通过光谱对比,发现以二甲基亚砜为溶剂,主要吸收峰发生显著变化,说明以二甲基亚砜为溶剂,衍生物对锂离子的快速识别明显有效。A perylene diimide-crown ether derivative was designed and synthesized.Then were dissolved in DMF,DMSO and acetonitrile respectively,and their UV-visible absorption spectra were measured.Then a small amount of solid lithium iodide was added,and the UV-visible absorption spectra were measured separately.Through spectral comparison,it is found that when dimethyl sulfoxide is used as the solvent,the main absorption peak changes significantly,indicating that when dimethyl sulfoxide is used as the solvent,the derivative is significantly effective in quickly identifying lithium ions.
