Abstract

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 oxidative formation of disulfide linkages. The disulfide bonds were then cleaved under reductive conditions using dithiothreitol to discharge the molecules.
