Covalent perylene frameworks (CPFs) with melamine linkages have newly received rising interest for a variety of applications because of nitrogen-rich content and high stability. Herein, we account a new simple strategy to in situ attain nitrogen-rich covalent perylene frameworks (NRCPFs) as highly active photo platforms for in situ bond formation between aryldiazonium salts and heteroarenes (C-H bond arylation) through the controlled photoredox route.
