Facile approach for preparing porous organic polymers through Bergman cyclization

Author affiliations

Abstract

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.
