摘　　要：合成并研究了5-氯-3-硝基螺吡喃光谱性质及特异性识别。研究结果表明,5-氯-3-硝基螺吡喃具有溶剂化显色效应,闭环结构SP和开环结构MC分别在非极性和极性溶剂中稳定存在;该螺吡喃能从18种常见金属离子中特异识别出Ag+,且可识别四类共16种有机胺。The 5-chloro-3-nitrospiropyran was synthesized and its spectral properties as well as recognitions on metal ions and organic amines were conducted. The results showed that the spiropyran was solvochromic and the closed-loop structure was stable in non-polar solvents while in polar solvents it was the ring-opened structure MC. The spiropyran could specifically recognize Ag+ from eighteen common metal ions, and could recognize 16 kinds of organic amines and divide them into four classes.
