The synthesis and characterization of a novel family of main‐chain carbazole‐containingpolymers using copper‐catalyzed azide‐alkyne cycloaddition chemistry is reported. The reactions were performed under mild conditions using readily available copper catalysts and ligands, which afforded polymeric products with Mws up to 18 kDa. Using a range of techniques, the polymers were found to exhibit a glass

Graphical Abstract[GRAPHICS]Efficient double click methods for the synthesis of carbazole core diblock codendrimers were developed. The synthetic strategy involved the sequential double click reactions between an alkyne and an azide. The chromophore building block, N-octyl-3,6-diazidocarbazole, was chosen to serve as the azide functionalities for dendrimer growth via double click reactions with the alkyne-functionalized PAMAM dendrons as hydrophilic dendron and alkyne-functionalized Frechet-type dendrons as hydrophobic dendron. The structure of diblock codendrimers was confirmed by H-1- and C-13-NMR spectroscopy, IR spectroscopy, mass spectrometry, and GPC analysis.
