摘　　要：采用三乙醇胺为核的三向聚酰胺胺树形分子为模板,以N,N-二甲基甲酰胺(DMF)为溶剂,以硼氢化钠为还原剂,利用模板法制备树形分子与金纳米簇复合物.实验结合UV-vis和FT-IR对树形分子与HAuCl4在络合与还原阶段的相互作用进行了分析,并结合PSS(particle sizing system)和TEM对纳米金溶液的粒径及其分布进行了表征,综合判断出纳米金的生成.Gold nanoclusters were prepared by reduction of HAuCl4 with NaBH4 in the presence of three-direction polyamidoamine（PAMAM） dendrimer with a triethanolamine core（G1.5） in N,N-dimethylform amide.The interaction of HAuCl4 and G1.5 was investigated by UV-vis and FT-IR spectroscopies,and particle sizing system（PSS） and TEM were used to study the particle size and diameter distribution.Gold nanoclu sters had been synthesized by using G1.5 as template.
