| 摘 要： | 荧光化学敏感器（ＦｌｕｏｒｅｓｃｅｎｃｅＣｈｅｍｉｃａｌＳｅｎｓｏｒ，ＦＣＳ）是近年来得到迅速发展用以检测外来物种的一种新方法．一般说来，它由下列三个部分所组成：（１）外来物种的接受体部分，（２）荧光发射部分，（３）连接体部分．作为接受体部分的设计是决定ＦＣＳ在检测物种时的选择性或专一性的关键所在．因此其设计往往要和拟检测物种的结构特征相联系．荧光发射部分的选定则和ＦＣＳ的灵敏度相关，适当的选择会使ＦＣＳ的接受体在接受外来物种后，能灵敏地引起荧光发射强度或特征发射波长的变化，使人们可敏锐地发觉所…

| Abstract: | A series of naphthylmethyl polyethylenepolyamine have been synthesized in this work.Its complexation with zinc salts in different solvents and the type of formation of the complex were investigated by means of fluorescence spectra.The results showed that naphthylmethyl polyethylenepolyamine is a good fluorescence chemical sensor for the testing of foreign zinc ion.A 1:2 stoichiometric complex was found in the solution of compound 3 with zinc acetate.But a 1:1 complex was formed when it reacted with zinc chloride in solution. An obvious excimer emission could be observed in the fluorescence spectrum of compound 3 with zinc chloride. |
