a convenient, one-pot method for the synthesis of diazonium salt has been developed by the sequential diazotization of aromatic amines with nano2, polymer- supported periodic acid (ppia) and 2-naphthole under solvent-free conditions at room temperature. by using this method, several types of aromatic amine, containing electron-withdrawing and electron-donating groups, were rapidly converted to ...

Cell-penetrating peptides (CPPs) and their synthetic mimics (CPPMs) represent a class of molecules that facilitate the intracellular delivery of various cargo. Previous studies indicated that the presence of aromatic functionalities improved CPPM activity. Given that aromatic functionalities play prominent roles in membrane biology and participate in various π interactions, we explored whether ...
