Schiff‐base type porous polymer sheets with ultrahigh nitrogen content have been successfully synthesized by utilizing aminated graphene oxide as a 2D structure‐directing template via dynamic covalent chemistry. Nitrogen‐enriched porous carbon nanosheets were thus prepared by thermal pyrolysis of the 2D porous polymers, showing exceptionally high capacitance up to 424 F g −1 at 0.1 A g −1 in 6 m KOH, superior to that of porous carbons without graphene involved.
