摘要：
A simple orthogonal convergent methodology for the synthesis poly(aryl ether amide) dendrons was introduced. It was found that nucleophilic aromatic substitution and amidation were chosen as orthogonal coupling reactions because each coupling reaction do not interfere with the other coupling reaction. It was observed that all poly(aryl ether amide) dendrons show enhanced solubility resulting from dendritic macromolecular structures compared with the linear or hyperbranched poly(aryl ether amides). The results show that each single orthogonal reaction produced next generation dendrons with high purity after simple precipitation.
