Description

Application

o-Phenylenediamine can be used in the synthesis of:

• Various benzimidazole derivatives that are structural units of several bioactive drug substances and pigments.
• N-doped colloidal graphene quantum dots (QDs), which can electrochemically catalyze the oxygen reduction reactions.
• N-doped graphene nanoplatelets from simple solution edge-functionalization for n-type field-effect transistors.
• N-heteroacenes (azaacenes) that are good candidates as active materials for organic thin film transistors.
