摘　　要：以乙二胺为核,采用发散法合成了0.5G-2.5G聚酰胺-胺(PAMAM)树形大分子,并利用紫外分光光度计对其进行了分析。结果表明,0.5G-2.5GPAMAM在400nm附近出现紫外吸收峰,溶液浓度和pH值对其紫外光谱均有影响。Disperse method was used to synthesize 0.5-2.5 generation polyamidoamine（PAMAM）Dendrimers with ethylenediamine as core.PAMAM was investigated by ultraviolet spectroscopy. The results indicated that 0.5- 2.5 generation PAMAM had ultraviolet absorption peaks at about 400 nm.Ultraviolet spectroscopy of PAMAMs was influenced by concentration and pH value of their water solution.
