Synthesis and catalytic properties of imidazole-functionalized poly(propylene imine) dendrimers

Abstract

The synthesis and characterization of third- and fifth-generation poly(propylene imine) dendrimers terminated with imidazole moieties is reported. Functionalization was achieved using simple peptide coupling reagents. These materials were characterized by MALDI-MS, NMR, and titration. The use of these endgroupfunctionalized dendrimers as catalysts for the hydrolysis of 2,4-dinitrophenyl acetate is described. Molecular simulations provide a basis for interpreting the catalytic data.
