1.合成了一种含萘基(NG1)的聚胺酯树枝状大分子作为金属离子的荧光化学传感器。在乙腈溶液中分别加入Ag^+、Al^&lt；3+&gt；、Ba^&lt；2+&gt；、Ca^&lt；2+&gt；、Cd^&lt；2+&gt；、Co^&lt；2+&gt；、Cu^&lt；2+&gt；、Fe^&lt；3+&gt；、Mg^&lt；2+&gt；、Ni^&lt；2+&gt；和Zn^&lt；2+&gt；当加入Al^&lt；3+&gt；，Cu^-lt；2+&gt；和Zn^&lt；2+&gt；时，NG1的荧光光谱发生了较大的变化。2.合成了一种金属离子荧光化学传感器。我们研究了N8对金属离子的识别作用。加入Al^&lt；3+&gt；，Zn^&lt；2+&gt；，Cd^&lt；2+&gt；和Ni^&lt；2+&gt；时，N8的荧光光谱发生了较大的变化。

1.A poly(amine ester) dendrimer with naphthyl units (NG1) has been synthesized as a fluorescent chemosensor for metal ions. We investigated the metal ion recognition of NG1 by adding each Ag^+, Al^<3+>,Ba^<2+>,Ca^<2+>,Cd^<2+>,Co^<2+>,Cu^<2+>,Fe^<3+>,Mg^<2+>,Ni^<2+>, and Zn^<2+> in acetonitrile solution. Large changes were observed in the fluorescence spectra of NG1 on addition of Al^<3+>,Cu^<2+>, and Zn^<2+>.2.Poly(amide amine) dendrimer with naphthyl units (N8) as a fluorescent chemosensor for metal ions was synthesized. We investigated the metal ion recognition of N8. Large changes in the fluorescence spectra of N8 were observed upon the addition of Al^<3+>,Zn^<2+>,Cd^<2+> and Ni^<2+>.
