摘　　要：以乙二胺(EDA)、三羟甲基丙烷三丙烯酸酯(TMPTA)和苯甲酸(BZA)为原料,合成了树枝状荧光聚(胺-酯)(PAE-BZA)。研究了Fe^(3+)、Cu^(2+)、Co^(2+)、Zn^(2+)对其荧光性能的影响。结果表明:溶液中的Fe^(3+)、Cu^(2+)及Co^(2+)对PAE-BZA的荧光具有猝灭效应;溶液中的Zn^(2+)对PAE-BZA的荧光具有先增强后减弱作用;当PAE-BZA浓度分别为6.4和5.2μmol/L时,吸附曙红B和甲基橙浓度达到恒定,且每个PAE-BZA分子分别吸附曙红B和甲基橙为1和3个。Dendritic fluorescence poly（amine-ester）（PAE-BZA） is synthesized from ethylenediamine （EDA）, trimethylolpropane triacrylate （TMPTA） and benzaldehyde （BZA）. The effects of Fe^3＋, Cu^2＋ , Co^2＋ , Zn^2＋ on fluorescence properties of PAE-BZA are studied. Fluorescence of PAE-BZA is quenched by Fe^3＋ , Cu^2＋ and Co^2＋ in the solution, fluorescence of PAE-BZA is first increased then decreased by Zn^2＋ in the solution. At the same time, PAE-BZA of Eosine B and methyl orange dye with adsorption properties are found. When the concentration of PAE-BZA was 6.4 × 10^-6 and 5.2 × 10^-6, the of concentration Eosine B and methyl orange were reached constant. Each PAE-BZA molecular respectively adsorbed one Eosine B and three methyl orange dye.
