以二乙三胺和丙烯酸甲酯为原料，采用简单的一锅法和工业合成法合成了超支化聚酰胺胺(h-PAMAM)。用傅立叶变换红外光谱、特性粘度和荧光技术对反应过程和产物进行了研究。结构不良的h-PAMAM与定义良好的第二代或第三代聚酰胺胺(PAMAM)树枝状大分子具有相似的化学和物理性质。其强荧光性质受pH值、溶剂、浓度、端基等因素的影响。
Hyperbranched poly(amido amine) (h-PAMAM) was synthesized from different feed ratios of diethylene triamine and methyl acrylate by the simple one-pot and commercial synthesis method. Reaction procedures and products were intensively studied by FTIR, inherent viscosity and fluorescence techniques. The ill-structured h-PAMAM shared similar chemical and physical properties with well defined poly(amido amine) (PAMAM) dendrimers in generation 2 or 3. Its strong fluorescence properties were influenced by pH values, solvents, concentrations, terminal groups and other factors.
