1.合成了一种具有萘基单元的聚胺酯树状大分子（NG1），作为金属离子的荧光化学传感器。通过在乙腈溶液中分别加入Ag^+、Al^<3+>、Ba^<2+>、Ca^<2+>、Cd^<2+>、Co^<2+>、Cu^<2+>、Fe^<3+>、Mg^<2+>、Ni^<2+>和Zn^<2+>，研究了NG1对金属离子的识别。加入Al^<3+>、Cu^<2+>和Zn^<2+>后，NG1的荧光光谱发生了较大变化。合成了具有萘基单元（N8）的聚（酰胺胺）树状大分子作为金属离子荧光化学传感器。我们研究了N8的金属离子识别。在加入Al^<3+>、Zn^<2+>、Cd^<2+>和Ni^<2+>后，N8的荧光光谱发生了较大变化。

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+>.
