Abstract

A series of Fréchet dendronized poly(p‐benzamide)s have been synthesized. To attach the dendron‐functionalities to the poly(p‐benzamide) backbone, a propargyl side chain was introduced to p‐aminobenzoic acid. Then, copper catalyzed azide‐alkyne cycloaddition was used to click a first generation (G~1~), respectively, a second generation (G~2~) Fréchet‐dendron azide onto the amino acid monomer. The resulting amino acids were polymerized using triphenylphosphite to obtain a poorly organo‐soluble G~1~‐dendronized polymer and a non‐aggregating G~2~‐dendronized polymer showing good organo‐solubility. Furthermore, a strictly alternating non‐aggregating G~1~‐TEG‐dendronized polymer with good organo‐solubility was synthesized. The aggregation behavior of these polymers was investigated by dynamic light scattering.
