Synthesis and Fluorescence properties of Hyperbranched Poly(amido amine) with New Fluorescence-emitting Moieties

摘要

Hyperbranched poly(amido amine) (PAMAM) was prepared by Michael addition reaction of methyl acrylate (MA) and ethidenediamine (EDA). The result showed that fluorescence intensities increased with increasing the molecular weight. Importantly, the present work showed a new kind of fluorescence-emitting moieties in the fluorescence spectra, which different from the results as reported in PAMAM dendrimers.
