Functionalized porous carbons have received increased attention in both gas and
supercapacitive energy storage. We report heteroatom-rich porous carbons derived from two
conjugated microporous polyaminoanthraquinone networks via a straightforward pyrolysis
pathway, showing high contents of nitrogen (N, max. 5.2 wt%) and oxygen (O, max. 8.3
wt%), uniform micropore (~0.6 nm) and large surface area (1165 m2 g-1). In comparison to the
polymer precursors, the resulted porous carbons exhibit much improved CO2 uptake capacity
of 14.1 wt% at 1 bar maintaining an impressive reversible CO2 uptake upon 50 times use.
More importantly, they can be applied for efficient supercapacitors with high energy storage
capacity (200 F g-1 at 0.5 A g-1), fast charge/discharge rate (charge to 158 F g-1 with only 25 s),
and excellent stability (retain 98.5% capacity after 6000 cycles).
