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.
