The development of new dendritic fluorescent chemosensors as analytical reagents.

1.合成了一种含萘基单元的聚胺酯树状大分子（NG 1），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^<3+>、Ba^<2+>、Ca^<2+>、Cd^<2 +>、Co^<2+>、Cu^<2 +>、Fe^<3+>、Mg^<2+>、Ni^<2+>和Zn^<2+>，研究了NG 1对金属离子的识别。研究了含萘基单元的聚酰胺-胺树枝状大分子（N8）对金属离子的荧光化学传感作用，发现其荧光光谱随Al^<3+>、Cu^<2+>和Zn^<2+>的加入而发生明显变化。我们研究了N8的金属离子识别。当加入Al^<3+>、Zn^<2+>、Cd^<2 +>和Ni^<2+>时，N8的荧光光谱发生了很大的变化。

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+>.
