采用烯二炔单体通过Bergman环化制备微孔有机聚合物。这种简便的合成方法从单一单体开始，通过热处理过程，在固相反应中不需要任何添加剂，例如催化剂、模板，甚至溶剂。所得微孔聚合物通过傅里叶变换红外、紫外-可见和固态13C CP/MAS核磁共振波谱进行表征。该聚合物的Brunauer-Emmett-Teller比表面积高达820 m2 g−1，而储氢量和二氧化碳吸收量分别达到1.76 wt%（1.0 bar和77 K）和10.5 wt%（1.0 bar和273 K）。预计这种新方法可以广泛应用于多孔有机聚合物的形成，作为伯格曼环化在材料科学中的全新应用。
An enediyne monomer is employed to prepare a microporous organic polymer through Bergman cyclization. The facile synthesis approach starts from a single monomer through a thermal process without the need for any additives, such as catalysts, templates, or even solvents, in the solid phase reaction. The obtained microporous polymer is characterized by Fourier transform infrared, ultraviolet-visible, and solid-state 13C CP/MAS nuclear magnetic resonance spectroscopy. The Brunauer–Emmett–Teller specific surface area of the polymer is as high as 820 m2 g−1, while the hydrogen storage and carbon dioxide uptake reaches 1.76 wt% (1.0 bar and 77 K) and 10.5 wt% (1.0 bar and 273 K), respectively. It is expected that this novel approach could be widely applicable in the formation of porous organic polymers as a brand new application of Bergman cyclization in materials science.
