摘　　要：以乙二胺、三羟甲基丙烷三丙烯酸酯和3,5-二羟基苯甲酸为原料,合成多羟基树枝状聚(胺-酯)(PAE-3,5-DAC),研究了Sn2+、Fe3+、Cu2+、Co2+、Zn2+对其荧光性能的影响。结果表明,溶液中的Sn2+、Fe3+、Cu2+及Co2+对PAE-3,5-DAC的荧光具有猝灭效应;溶液中的Zn2+对PAE-3,5-DAC的荧光具有先增强后减弱作用。同时测定了PAE-3,5-DAC水溶液对苯甲酸、水杨酸等难溶客体小分子的增溶性,结果表明,在质量浓度相同时,PAE-3,5-DAC对难溶客体小分子的增溶量远高于十二烷基硫酸钠(SDS)。Polyhydroxyl dendritic poly（amine-ester）（PAE-3,5-DAC） was synthesized from ethylenediamine,trimethylolpropane triacrylate and 3,5-dihydroxy benzoic acid.The effects of Sn2＋,Fe3＋,Cu2＋,Co2＋ and Zn2＋ on fluorescence properties of PAE-3,5-DAC were studied.Fluorescence of PAE-3,5-DAC was quenched by Sn2＋,Fe3＋,Cu2＋ and Co2＋ in the solution,fluorescence of PAE-3,5-DAC was first increased then decreased by Zn2＋ in the solution.The solubilization capacity on benzoic acid and salicylic acid hard-dissolved guest molecule was studied.It was found that PAE-3,5-DAC had more solubilization effect than sodium dodecyl sulfate（SDS） at same concent ration.
