Covalent attachment and release of small molecules from functional polyphenylene dendrimers

摘要

Herein, we report the synthesis of 2nd generation PPDs functionalized with free thiol moieties within the scaffold, which were used as anchor points for the covalent attachment of guest species (p-nitrophenol derivatives) through the pxidative formation of disulfide linkages. The disulfide bonds were then cleaved under reductive conditions using dithiothreitol to discharge the molecules.
