Abstract
Efficient double click methods for the synthesis of diblock codendrimers were developed. The synthetic strategy involved the sequential click reactions between an alkyne and an azide. The short core building block, 1,4-diazidobutane, was chosen to serve as the azide functionalities for dendrimer growth via click reactions with the alkyne-functionalized PAMAM dendrons as hydrophilic dendron and alkyne-functionalized Fréchettype dendrons as hydrophobic dendron. The structure of diblock codendrimers was confirmed by 1H and 13C NMR spectroscopy, IR spectroscopy, mass spectrometry, and GPC analysis.
