本文报道了一种新的合成方法，通过吡咯和二酮在酸存在下的缩合反应合成了新型多孔有机聚合物。所得聚合物的结构通过傅里叶变换红外光谱和固态13 C核磁共振光谱确认。所得到的聚吡咯网络具有超过650 m2 g-1的高Brunauer-Emmet-Teller比表面积，具有气体吸收能力，即在1.0巴下的氢气（在77 K下0.70重量%）、二氧化碳（在273 K下8.5重量%）和甲烷（在273 K下0.95重量%）。基于吡咯与二酮缩合反应的简便制备策略为制备多孔有机聚合物提供了一条途径。
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‐state13C nuclear magnetic resonance spectroscopy. The resulting polypyrrole network with high Brunauer–Emmet–Teller specific surface area over 650 m2g−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.
