Abstract:
A new synthesis route to novel porous organic polymers is reported based on condensation of pyrrole and diketone in the presence of an acid. The structure of obtained polymer is confirmed by Fourier transform infrared and solid‐state 13C nuclear magnetic resonance spectroscopy. The resulting polypyrrole network with high Brunauer–Emmet–Teller specific surface area over 650 m2 g?1, possesses gas uptake capacities, that is, hydrogen (0.70 wt% at 77 K), carbon dioxide (8.5 wt% at 273 K), and methane (0.95 wt% at 273 K) at 1.0 bar. The facile preparation strategy on the basis of condensation of pyrrole and diketone will provide an avenue to prepare porous organic polymers.
