Synthesis and Striking Fluorescence Properties of Hyperbranched Poly(amido amine).

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. [ABSTRACT FROM AUTHOR]
